[00:09.180 --> 00:11.040]  I love you too, Stank.
[00:11.460 --> 00:14.200]  I hope you enjoyed our little time by there.
[00:15.140 --> 00:18.960]  I'm Strom Carlson, and this is Black Ratchet,
[00:18.960 --> 00:23.240]  and welcome to Be Your Own Telephone Company with Asterisk.
[00:24.680 --> 00:29.180]  Apparently Alex thought that rated this a bullshit presentation, so...
[00:30.040 --> 00:31.660]  Yes, we're very proud of that fact.
[00:36.780 --> 00:39.900]  See, if Alex thought that we're actually here, we'd give him the payphone,
[00:39.900 --> 00:43.900]  but I guess he's not, so you lose, Alex. Sorry.
[00:47.280 --> 00:48.800]  So, let's get started.
[00:48.820 --> 00:51.780]  Actually, before we get started, I just want to test the phone
[00:51.780 --> 00:53.860]  to make sure that our dial tone's the right volume.
[01:54.760 --> 01:56.560]  Alright, so let's get started.
[01:57.900 --> 02:00.340]  Seems like I've got these cords in the right places.
[02:01.060 --> 02:04.640]  So, first off, what is Asterisk? What is this damn thing?
[02:05.960 --> 02:08.560]  How many of you have no clue what Asterisk actually is?
[02:11.080 --> 02:15.040]  Sweet. You're in for fun. Lots of fun.
[02:15.680 --> 02:17.020]  What is Asterisk?
[02:17.160 --> 02:21.020]  Asterisk is a free, open-source PBX that runs on Linux.
[02:21.400 --> 02:22.960]  It is the best thing since sliced bread.
[02:22.960 --> 02:25.000]  How many of you don't know what a PBX is?
[02:26.720 --> 02:28.500]  All my phones have their friends in the front.
[02:29.080 --> 02:32.040]  PBX is a private brand exchange. It's a telephone system.
[02:32.040 --> 02:34.620]  In case you hadn't guessed, it's a talk about telephones.
[02:35.180 --> 02:38.780]  It was originally written by Mark Spencer of Digium back in 1999.
[02:38.780 --> 02:41.120]  It's been upgraded significantly since then.
[02:41.120 --> 02:43.920]  It's now version 1.0.8. It's a stable 1.0.
[02:45.380 --> 02:47.620]  1.0.9 is a stable 1.0?
[02:47.780 --> 02:48.840]  Yeah. Okay.
[02:53.700 --> 02:56.700]  We just ran the latest bleeding edge version.
[02:56.720 --> 02:59.540]  So, why Asterisk? Well, first off, it's free!
[03:01.600 --> 03:03.040]  And that's the cool part.
[03:03.040 --> 03:09.380]  A typical PBX for a business will cost you in the 5-digit range just for the hardware.
[03:09.620 --> 03:11.580]  And when you set it up, it will cost you even more.
[03:11.660 --> 03:15.040]  So if you can do this yourself, and this is very easy to do yourself,
[03:15.040 --> 03:17.020]  it will save you a lot of money if you're running a company.
[03:17.020 --> 03:20.620]  And if you're a hobbyist, it's really cool because you can set up your own phone network
[03:20.620 --> 03:23.060]  and call each other for free, and we'll get into that.
[03:23.580 --> 03:25.720]  It runs on commodity PC hardware.
[03:25.720 --> 03:30.820]  In fact, this little tiny laptop that Ratchet is typing on right now
[03:30.820 --> 03:33.460]  is our Asterisk PBX for the presentation.
[03:34.380 --> 03:37.740]  There's broad support for VoIP protocols and hardware.
[03:38.040 --> 03:41.760]  It's easy to interconnect with other Asterisk boxes and form your own network.
[03:41.760 --> 03:44.300]  It's configurable to do almost whatever you want it to do.
[03:44.300 --> 03:48.820]  So you can tweak it to your needs, you can write your own code to interface with things if you need to.
[03:49.360 --> 03:54.020]  Unfortunately, it won't do your dishes, but it comes close.
[03:54.020 --> 03:57.420]  We're working on the dish dial tone module.
[04:04.980 --> 04:07.780]  So let's get into the hardware of Asterisk.
[04:08.500 --> 04:11.880]  Asterisk will run on surprisingly out-of-date stuff.
[04:12.120 --> 04:18.160]  If you go to VoIPinfo.org, there's a wiki there with all sorts of information on VoIP and especially Asterisk.
[04:18.160 --> 04:22.720]  And one of the pages is this page where people post what they've gotten Asterisk to do.
[04:22.720 --> 04:24.780]  And they stress test Asterisk on various hardware.
[04:25.260 --> 04:32.220]  Someone running a 133 MHz Pentium 1 with 16 MB of RAM got 3 concurrent SIP calls going at the same time.
[04:32.960 --> 04:35.460]  And any PC you have lying around will work.
[04:35.540 --> 04:42.060]  Someone posted that they got a 2.4 GHz P4 with 512 MB of RAM to do 790 simultaneous calls.
[04:43.860 --> 04:49.600]  So you'll hit your bandwidth limit far more quickly than you'll hit the limit of your hardware.
[04:52.200 --> 04:56.640]  Here's a sample Asterisk installation. This is actually my rack behind my desk at home.
[04:56.800 --> 04:59.620]  So here's my Asterisk box in the corner.
[05:00.780 --> 05:03.940]  Thanks, thanks. I get told that a lot.
[05:06.180 --> 05:07.460]  I beg your pardon?
[05:09.180 --> 05:11.540]  Yeah, I did get the rack at Costco, actually.
[05:12.600 --> 05:17.280]  So there's the Asterisk box chilling into my mail server, my web server, my NAS box, and everything.
[05:17.860 --> 05:24.560]  There are Sun machines here. Asterisk is running on the PC, but people have gotten it to work on Sun machines running Linux.
[05:24.560 --> 05:28.420]  And I think someone got it to run on Solaris running on Sun hardware as well.
[05:30.360 --> 05:32.640]  So, yes.
[05:34.820 --> 05:40.180]  They all work. We'll have a Q&A session at the end, so we'll do that.
[05:41.000 --> 05:46.860]  There are many methods for connecting your telephones to Asterisk.
[05:46.860 --> 05:53.120]  You can get either an IP telephone, or you can connect regular analog telephones to Asterisk.
[05:53.920 --> 05:58.140]  There are IP telephones you can buy second-hand on the market. They're not all that expensive.
[05:58.260 --> 06:01.300]  This is the Cisco 7960. This is an IP phone.
[06:01.840 --> 06:08.300]  You can get those for about $250 online. In fact, I looked on eBay. I think I saw them going used for $150.
[06:09.520 --> 06:14.860]  If you look for deals, I've gotten one for $120. That's as low as they go right now in current market conditions.
[06:18.160 --> 06:19.860]  There's the... go ahead.
[06:20.060 --> 06:22.100]  You don't want to know what I had to do for that.
[06:24.980 --> 06:28.640]  There's the Polycom IP600, which is considered the other really good phone.
[06:28.640 --> 06:31.660]  These two are considered probably the premium-deployed telephones.
[06:31.660 --> 06:34.120]  And that's $250 online on eBay.
[06:34.520 --> 06:39.840]  There are crappy telephones you can get. You can get the Grandstream Budget Home 100, used about $40.
[06:39.840 --> 06:43.860]  It's roughly equivalent to that $9.95 phone you buy at the drugstore
[06:44.640 --> 06:46.980]  that falls apart before you even get it home.
[06:47.040 --> 06:50.260]  But it's a VoIP phone, so if you need a cheap VoIP phone, that'll work.
[06:50.540 --> 06:55.700]  And right in the mid-range, there's the Snom 190, which is about $150, $175.
[06:55.940 --> 06:58.500]  The prices have come down since we threw these slides together.
[06:59.120 --> 07:05.280]  And, I mean, there are hundreds of manufacturers making phones for Asterisk and just VoIP in general.
[07:05.280 --> 07:07.760]  So you can look around and find all sorts of stuff.
[07:12.220 --> 07:16.700]  Most VoIP phones are built the same. We'll get into that, actually, in the protocol section.
[07:16.700 --> 07:20.920]  So I'm actually going to ask you to hold your questions until the Q&A session at the end.
[07:20.920 --> 07:25.280]  And we'll have a queue at the telephone over there for you to ask your questions via telephone.
[07:27.440 --> 07:29.100]  You know the cool stuff's coming later.
[07:29.260 --> 07:33.800]  You can also get little terminal adapters if you want to plug your analog telephones in.
[07:34.320 --> 07:39.000]  You can buy one from Digium that speaks Asterisk's native protocol called EECS.
[07:39.080 --> 07:41.240]  And that's called the EECS-E. And I think I have one here.
[08:01.880 --> 08:09.980]  This is the EECS-E. A little tidy thing. You plug in an analog telephone in one end and you plug your Ethernet connection in the other end.
[08:09.980 --> 08:13.460]  And your analog phone is now a VoIP phone. This is $100.
[08:14.760 --> 08:22.040]  You can also get the Sephora SPA-2002. We've got those here running. And these are about $70.
[08:22.040 --> 08:25.780]  You can plug two Vana Ratchet.
[08:29.540 --> 08:36.100]  These speak SIF instead of EECS. You can plug two analog telephones into these and get two dial tones and that's about $70.
[08:36.100 --> 08:44.500]  You can get the Grandstream HandyTone 286 for about $65. That only does one, I think, that speaks SIF.
[08:44.500 --> 08:51.460]  And the old Cisco ATA-186, which is the one that Vonage used to send out, is about $50 online.
[08:51.660 --> 09:02.240]  You can also... there's tons more of these. There's one... the adapter that Packet 8 used to send out, the DTA-310, you can find those about $30 used online.
[09:02.240 --> 09:07.960]  And although you can't really get them working as they are, you can reflash the firmware and they become just generic SIF adapters.
[09:08.480 --> 09:10.360]  There's details for that on the website.
[09:11.260 --> 09:21.460]  You can also buy something called a Zaptel card. And these are cards you put in your asterisk box and you connect analog telephones and telephone lines to these cards.
[09:21.560 --> 09:26.420]  The one on the top is the TDM-400P. That has four little modules on it.
[09:26.420 --> 09:34.140]  You can select either FXS, which are dial tones, or FXO, which are telephone line interfaces, and put them on the card and arrange them any way you like.
[09:34.880 --> 09:47.500]  The bottom one is a T1 card, and you can... there are two versions of FXO, 405 and 410P, and the 411 and 406 have echo cancellation built into them.
[09:48.000 --> 09:57.540]  And so you can bring four primary rate ISDN interfaces into that and have 96 channels of voice going out of your asterisk box.
[09:57.540 --> 10:05.140]  Or, you know, if you've got a whole bunch of analog phones, you can get a channel bank and plug the channel bank into the T1 for your stations.
[10:05.140 --> 10:08.960]  So you can have 96 stations running off of one asterisk box with four channel banks.
[10:10.960 --> 10:13.540]  So, what are you talking about?
[10:16.180 --> 10:21.480]  Let's get into some of the protocols that asterisks use to talk to the network.
[10:27.800 --> 10:35.380]  Those are really hard to find, in my opinion. I mean, I've looked for them because I thought they were really cool, but I could not find them anywhere.
[10:35.380 --> 10:39.000]  I searched eBay for about a week, and I finally gave up in frustration.
[10:43.760 --> 10:44.920]  Oh, that's cool.
[10:46.560 --> 10:53.760]  Okay, for those of you who didn't hear, apparently the Linksys TAP2 is the same way as the Sapura 2000.
[10:53.760 --> 10:57.600]  It can or can't, except for it cannot be flashed permanently.
[10:57.600 --> 11:01.600]  Anyway, getting back to interconnecting asterisks, let's go adjust this.
[11:05.300 --> 11:11.860]  The main protocol for interconnecting voice over IP calls is called SIP. It stands for Session Initiation Protocol.
[11:11.860 --> 11:17.600]  It's a signaling protocol only. It only signals and sets up calls.
[11:17.600 --> 11:24.460]  All it does is contact your box and say, hey, I have a good call for you. You might want to connect to it. It's on this IP address.
[11:24.460 --> 11:33.400]  At which point, it connects to the IP address with a protocol called RTP, which stands for Real-Time Transport Protocol.
[11:34.480 --> 11:40.180]  It was developed by the ITF, not ITU. It uses URLs instead of telephone numbers.
[11:40.180 --> 11:50.300]  For example, you won't connect to 3-1-1-5-5-5-2-3-6-8. You'll enter it into SIP, stromcharleston.com, which doesn't work on Thread.
[11:50.560 --> 11:57.160]  It's intended to be a peer-to-peer protocol. It's not like a general server. It goes to my box next to Strom's.
[11:57.300 --> 12:05.340]  It doesn't have to contact anybody for it to work. There are certain caveats to that. We'll get into those later.
[12:05.340 --> 12:15.220]  The main advantage of SIP is that it's very ubiquitous. It's supported by everybody. If you talk about VoIP, anything post-1998, it uses SIP.
[12:16.060 --> 12:25.180]  Packet 8, Broad Voice, essentially all the major providers use SIP, with the exception of AT&T called Vantage, which I'll cover later.
[12:25.420 --> 12:32.760]  It does not play well with NAT. It's very hard to actually set up with NAT. You have to start poking holes in your firewall for the RTP.
[12:32.760 --> 12:40.900]  And, for example, if you start connecting out to another box, say I'm behind NAT and I try to call Strom, it'll say, oh, connect to my box.
[12:40.900 --> 12:49.700]  I'm at 192.168.0.252, and Strom's loss of VoIP. So there's a lot of workarounds for it.
[12:49.700 --> 12:54.660]  What you have to do is you have to tell it to, you know, this is my external IP address. Use this for everything.
[12:54.980 --> 13:00.060]  Don't care about whatever your IP address is. However, in my opinion, it's a bit of a kludge.
[13:00.880 --> 13:07.700]  The other protocol, before there was SIP, there was H.323. It was developed in 1996 by the ITU.
[13:08.600 --> 13:16.300]  It's really far more similar to traditional protocols that are used by telephone networks, as opposed to SIP.
[13:16.620 --> 13:20.540]  Like, for example, SS7 or something. It's more similar to that.
[13:20.560 --> 13:28.180]  Again, it uses RTP for media transport, and it's used internally a lot by inter-exchange carriers.
[13:28.180 --> 13:33.100]  And it's very unpopular in the VoIP world, because it isn't a fair setup.
[13:33.600 --> 13:36.420]  And it's, like I said, a major pain in the ass to get it working correctly.
[13:36.980 --> 13:37.980]  Hold on.
[13:38.360 --> 13:43.540]  Although, by the way, although this is a telephone talk, please turn your ringers off. Thank you.
[13:43.960 --> 13:46.880]  Come on, I figured let's discriminate her against telephone users.
[13:47.640 --> 13:53.720]  We actually were hanging, Strom was hanging out in Pound Asterisk one day on IRC.3dome.net, for anyone interested.
[13:53.720 --> 13:58.780]  And JerJer, who's one of the major contributors in Asterisk, made the following quote.
[13:58.780 --> 14:01.840]  Just don't use H3.3, and all your problems will be solved.
[14:01.840 --> 14:04.120]  Which, technically, is correct.
[14:05.120 --> 14:09.960]  Now, for Asterisk, there's a main protocol, and as you can tell, it's based on Asterisk.
[14:09.960 --> 14:11.840]  It's called intra-asterisk exchange.
[14:11.840 --> 14:15.320]  It was developed by Mark Spencer of Digium, the guy who wrote Asterisk.
[14:15.320 --> 14:17.740]  And it covers both signaling and media transport.
[14:17.740 --> 14:20.080]  It's a very streamlined, very simple protocol.
[14:20.080 --> 14:26.560]  What Mark wanted to do is he wanted to, you know, took a look at SIP, took a look at H3.23, and said,
[14:26.560 --> 14:29.240]  Boy, these are crap. Let's go design a mining protocol.
[14:29.640 --> 14:32.780]  It does not suffer from NAT traversal issues.
[14:32.960 --> 14:38.920]  For example, I'm behind a firewall I call Strom, and, you know, it knows that where I'm coming from, you know,
[14:39.420 --> 14:40.660]  it knows where to connect.
[14:40.660 --> 14:44.560]  It doesn't actually, you know, say, hey, I have an IP address here, which could be wrong.
[14:45.420 --> 14:50.000]  Data signaling happened via UDP on port 4569.
[14:50.000 --> 14:52.720]  That's the only thing you have to open up in your firewall as opposed to RTP,
[14:52.720 --> 14:55.240]  which I think you have to open about 15,000 ports for.
[14:55.760 --> 14:57.980]  Very well supported by Asterisk.
[14:59.420 --> 15:02.840]  However, the support in terminal equipment is very rare.
[15:02.840 --> 15:08.020]  The only ETA that supports it is the ICSI by Digium that makes it.
[15:08.240 --> 15:12.380]  I've also noticed that one phone recently started to support it.
[15:12.380 --> 15:14.100]  It's called a NetWeb302.
[15:14.100 --> 15:15.820]  It's actually made in China.
[15:16.300 --> 15:18.880]  And the only place you can get it is someplace in Delaware.
[15:19.640 --> 15:20.440]  Telephone.
[15:20.880 --> 15:22.600]  Could you shut off the ringer, please?
[15:22.860 --> 15:24.420]  I'm testing for later.
[15:24.960 --> 15:26.560]  The nerve of some people.
[15:29.720 --> 15:35.560]  It's a protocol for many PSTN termination providers because, you know, a lot of PSTN termination providers,
[15:35.560 --> 15:36.800]  they use Asterisk.
[15:36.800 --> 15:37.840]  It all works.
[15:37.840 --> 15:38.460]  Just set it up.
[15:38.460 --> 15:39.500]  It's fire and forget.
[15:39.660 --> 15:42.800]  I think I set it up in one of my accounts about a year ago.
[15:42.800 --> 15:44.520]  I haven't touched configuration settings.
[15:44.520 --> 15:45.700]  It just works.
[15:46.820 --> 15:50.820]  The other protocols are the Media Gateway Control Protocol, MGCP.
[15:50.820 --> 15:52.360]  That's the other protocol I was talking about.
[15:52.360 --> 15:54.140]  It's used by AT&T called Vantage.
[15:54.340 --> 15:56.380]  I'm not sure if they still use it, but they did.
[15:56.560 --> 16:03.700]  I bought an old ETA firm on eBay, and I had to reflash it and do all kinds of annoying things to actually get it working with Asterisk.
[16:03.700 --> 16:05.100]  But the support is there.
[16:05.400 --> 16:09.300]  The other thing is Cisco's Skinny Client Control Protocol.
[16:09.800 --> 16:11.320]  It's used by Cisco phones.
[16:11.320 --> 16:12.340]  This actually uses SIP.
[16:12.340 --> 16:13.940]  This doesn't use SCCP right now.
[16:13.940 --> 16:18.860]  You can choose with the Cisco phones to use either SIP or SCCP.
[16:18.860 --> 16:20.280]  They're different firmware images.
[16:20.900 --> 16:23.500]  Not all Cisco phones support SIP.
[16:23.500 --> 16:30.760]  For example, I have an older version that was made in the early 2000s, and it only uses SCCP.
[16:30.760 --> 16:32.000]  There's support for it.
[16:32.000 --> 16:34.520]  It's not the best in the world, but it works.
[16:34.520 --> 16:39.060]  I mean, I can only have one line on the phone, and three-way calling is an issue.
[16:40.960 --> 16:46.200]  There are two different SCCP implementations for Asterisk, and they both kind of suck.
[16:47.200 --> 16:50.140]  Chan SCCP2 doesn't suck as bad.
[16:53.140 --> 16:55.900]  But that's kind of like being the tallest midget.
[16:55.900 --> 16:56.960]  Yeah, exactly.
[17:00.200 --> 17:03.960]  Since Strom is the Kodak Nazi, we'll just sort of choose this one for him.
[17:03.960 --> 17:07.020]  I'm a Kodak Nazi now, in addition to being a spelling and grammar Nazi.
[17:12.920 --> 17:13.980]  It's a compliment.
[17:15.220 --> 17:23.680]  So anyway, basically, there are many different codecs that you can use to encode voice with Asterisk.
[17:23.680 --> 17:27.540]  And we're going to go over what they are, what they do, and what they sound like.
[17:28.920 --> 17:32.280]  In order to understand codecs, you need to understand how digital audio works.
[17:32.280 --> 17:34.760]  How many of you don't really know how digital audio works?
[17:36.480 --> 17:37.360]  Okay.
[17:37.360 --> 17:41.060]  Well, I don't want to see too many hands go up, so I'll kind of go over this quickly then.
[17:41.260 --> 17:46.120]  Basically, you have an analog waveform, and this is divided up into a number of little slices of time.
[17:47.260 --> 17:53.700]  So you have an analog bunch of different slices of analog audio.
[17:53.820 --> 17:58.080]  These are pulses of analog amplitudes called pulse-amplitude modulation.
[17:58.140 --> 18:00.300]  So you've got time division, but it's still analog.
[18:00.780 --> 18:06.640]  What happens is these values are then quantized into digital values.
[18:06.640 --> 18:08.140]  This is called pulse-code modulation.
[18:08.280 --> 18:12.400]  PCM is what you use when you talk on a telephone, on a regular telephone call.
[18:12.400 --> 18:14.700]  And it's also what you hear when you play a CD.
[18:16.440 --> 18:20.680]  So what happens is the values are quantized between 1 and negative 1.
[18:20.680 --> 18:26.740]  So depending on how much resolution you want to give to the values, you can specify more.
[18:26.740 --> 18:35.060]  The way mu law works, what mu law is, is the companding scheme that the analog telephone network uses.
[18:35.060 --> 18:39.680]  Whenever you make a regular long-distance call or a regular local call, you're using mu law.
[18:39.800 --> 18:45.900]  It's 64 kilobits per second, and what happens is it's a logarithmic scale.
[18:45.900 --> 18:51.440]  So more resolution is given to the lower amplitudes, where most of the voice frequency is,
[18:51.440 --> 18:54.260]  in order to give you the impression of 16-bit audio.
[18:54.740 --> 19:02.440]  What actually happens is it's only 8-bit audio, but it sounds far closer to 16 because of the companding.
[19:03.680 --> 19:08.820]  But however, for some people, 64 kilobits per second is still way too high for bandwidth.
[19:08.920 --> 19:16.080]  They're greedy, or they have less bandwidth, and they want to be able to send phone calls over less bandwidth.
[19:16.080 --> 19:20.200]  So there are many different ways of compressing this already compressed audio.
[19:21.860 --> 19:25.720]  Adaptive differential pulse code modulation, well first, differential pulse code modulation,
[19:25.720 --> 19:28.800]  uses 4 bits to describe the change from the last value.
[19:28.800 --> 19:33.020]  What mu law does, and PCM does, is it actually describes each value individually.
[19:33.020 --> 19:36.600]  This one it says, you know, go down 4, go up 2, and so on.
[19:37.300 --> 19:42.280]  Regardless of the original source resolution, regular DPCM just uses 4 bits.
[19:42.760 --> 19:48.380]  Adaptive differential PCM uses a varying number of bits, depending on the complexity of that sample,
[19:48.380 --> 19:52.420]  but it's still 32 kilobits per second, so they have to scrim somewhere.
[19:52.960 --> 19:56.120]  It sounds almost like mu law, but not quite.
[19:57.220 --> 20:02.540]  There's also LPC, and this is the basis for a lot of what you find in cell phone codecs.
[20:02.720 --> 20:06.020]  It's linear predictive coding, and it basically, it's pretty complex,
[20:06.020 --> 20:09.820]  but the basic thing is that it uses vocoders to compress speech.
[20:09.920 --> 20:13.840]  And it tends to work pretty well for speech, but there's a lot of electronic music nowadays
[20:13.840 --> 20:18.140]  that has the vocoders that have the singing synthesizer effect in the song.
[20:18.240 --> 20:22.820]  So, actually if you listen closely to talking on a cell phone, you'll begin to hear that.
[20:24.120 --> 20:28.540]  And you can actually use all these codecs with Asterisk and VoIP.
[20:29.620 --> 20:35.260]  So, again, voice on the PSTN is 64 kilobits per second, synchronous bandwidth for wireline telephones.
[20:35.580 --> 20:40.800]  North American uses mu law companding, most of the rest of the world uses a-law companding,
[20:40.800 --> 20:46.420]  which is almost identical, but slightly different, but for all intents and purposes, they sound exactly the same.
[20:47.000 --> 20:49.960]  If you're in 64 kilobits, if you're doing something called bit-probing,
[20:49.960 --> 20:56.080]  which is basically to give you supervision in band on one of the digital channels, you get 56 kilobits per second.
[20:56.080 --> 20:57.900]  But for the most part, it sounds the same.
[20:58.380 --> 21:03.380]  On mobile phones, you only get 4 to 13 kilobits per second for your voice.
[21:03.420 --> 21:05.780]  Which is why mobile phones sound so horrible.
[21:08.160 --> 21:11.460]  So, speech compression does have a lot of costs.
[21:11.460 --> 21:16.740]  First off, if you're running it on your Asterisk box, you have to transcode from mu law to the codec.
[21:16.740 --> 21:20.300]  And in order to be able to hear it, you have to transcode back from the codec to mu law.
[21:20.660 --> 21:23.700]  So, there's an increased CPU load that's required.
[21:23.700 --> 21:33.580]  That box that does 790 simultaneous calls, if you have it do GSM or one of the lower bandwidth codecs,
[21:33.580 --> 21:37.160]  I think that drops down to maybe 100 simultaneous calls.
[21:38.120 --> 21:42.120]  There's no guarantee that two pieces of equipment will speak the same codecs.
[21:42.120 --> 21:50.920]  A lot of times, the Seporas speak mu law and then G.726, I think.
[21:50.920 --> 21:52.640]  And then some of the other codecs.
[21:52.920 --> 21:55.000]  But, yes.
[21:56.940 --> 22:00.840]  But, you know, I think we're going to have to keep track of whether this is on or off.
[22:04.800 --> 22:06.240]  Thank you.
[22:06.540 --> 22:09.580]  But I think the EECSY only speaks mu law.
[22:10.400 --> 22:13.540]  And there are things that just speak certain codecs, and it's a mess.
[22:13.540 --> 22:18.180]  I mean, there's no guarantee that any pieces of equipment will be able to talk to each other unless you use mu law.
[22:18.660 --> 22:21.620]  Some codecs require licensing.
[22:21.900 --> 22:23.100]  Oh, and one thing I forgot to mention.
[22:23.100 --> 22:27.080]  If you're using non-standard fit rates for some of these codecs, then you're really in trouble.
[22:27.340 --> 22:29.860]  Some codecs require you to pay licenses to use them.
[22:29.860 --> 22:33.360]  There's a codec that... actually, we'll get into that in another slide.
[22:33.460 --> 22:35.800]  And codecs don't handle all kinds of sounds well.
[22:36.840 --> 22:39.840]  People will generally have trouble understanding certain words.
[22:39.840 --> 22:46.660]  A friend of mine says that every time he calls up a restaurant to make a reservation, they cannot understand the word north.
[22:47.260 --> 22:50.780]  It's always interpreted as something else from his mobile phone.
[22:50.780 --> 22:52.620]  No one ever gets north right.
[22:53.440 --> 23:02.020]  It's difficult to understand anyone who has poor diction, because these are designed under the assumption that people who are using them tend to enunciate well.
[23:02.020 --> 23:06.620]  And music on hold in codec land is absolute torture.
[23:06.960 --> 23:09.300]  You can gouge your eyes out if you really want to.
[23:09.300 --> 23:12.440]  I mean, I want to do that every time I'm on hold on my mobile phone.
[23:16.230 --> 23:18.490]  It is that bad sometimes.
[23:18.650 --> 23:22.670]  There's one we'll demonstrate that is that bad.
[23:22.670 --> 23:24.930]  There's a documented case in Arkansas.
[23:26.430 --> 23:29.130]  Apologies to anyone from Arkansas here.
[23:32.390 --> 23:34.970]  Here's the benefits. Each call uses less bandwidth.
[23:34.970 --> 23:36.450]  That's it.
[23:37.710 --> 23:41.730]  I wish there were more, because that slide looks really empty, but that's it.
[23:43.730 --> 23:45.630]  Here's what Asterisk supports.
[23:45.630 --> 23:49.810]  G.711, which is 64 kilobit per second ULA or ALAW companding.
[23:50.170 --> 23:53.790]  G.726, which is 32 kilobit per second ADPCM.
[23:54.070 --> 24:02.670]  G.729, which is 8 kilobit per second CSACELP, which is Conjugate Structure and Algebraic Code Excited Linear Prediction.
[24:02.670 --> 24:05.870]  That requires a license from Digium to purchase.
[24:06.450 --> 24:08.730]  We're going to demonstrate that codec later.
[24:08.910 --> 24:14.990]  Just in order for me to be able to call Ratchet's box and have one telephone conversation over the codec,
[24:14.990 --> 24:16.470]  we each had to pay $10.
[24:17.950 --> 24:21.650]  That's only for one call, so if you want to have more than one call using this codec,
[24:21.650 --> 24:24.030]  $10 a call for the licenses.
[24:25.850 --> 24:27.490]  Not per instance.
[24:27.490 --> 24:29.950]  Yeah, simultaneous calls.
[24:29.950 --> 24:35.810]  So if you only buy five licenses, you cannot have more than five simultaneous calls running on that codec.
[24:36.050 --> 24:40.230]  So if it were $10 a call, I think no one would use this thing.
[24:40.230 --> 24:44.010]  It would be like being back in those days.
[24:44.010 --> 24:46.050]  Or if it was developed by Microsoft.
[24:46.770 --> 24:51.750]  Here's the Internet Low Bandwidth Codec, which is a 13.3 kilobit per second linear prediction coding.
[24:51.750 --> 24:53.350]  This is what Skype uses.
[24:53.350 --> 24:57.390]  I mean, I've heard people rave about Skype. I hear it. I hear it just like ILBC.
[24:58.630 --> 25:04.050]  There's also Speaks, which is an open source codec. I think it's based on like the Ogg Vorbis stuff.
[25:04.330 --> 25:08.010]  And that's also 13.3 kilobit per second codec-sided linear prediction.
[25:08.330 --> 25:15.090]  And finally, for those of you who are on dial-up, there's LPC10, which is 2.4 kilobit per second.
[25:15.230 --> 25:18.350]  It sounds more ghastly than you can possibly imagine.
[25:20.730 --> 25:22.230]  Yes, that's the one.
[25:22.990 --> 25:31.790]  So in order to do a comparison of all these codecs, we figured we'd play some audio for you using each of the codecs.
[25:31.790 --> 25:37.250]  And so I decided, you know, I could do just talking, but that would get boring after about 25 seconds.
[25:37.250 --> 25:43.570]  So as proof that you can find anything on Craigslist, I found this song that this band let us use for free.
[25:43.570 --> 25:51.190]  So apologies if it's not up to your musical standard or your musical taste, but it's free, so be happy.
[25:51.190 --> 25:52.170]  I like it.
[25:52.170 --> 25:53.250]  I like it, too.
[25:53.250 --> 25:57.630]  It gets stuck in my head every time I hear it, and it's really annoying when he uses this version.
[25:57.630 --> 25:58.230]  Yes.
[26:00.890 --> 26:04.070]  Wait, so let me, um, let me cue it up here.
[26:13.420 --> 26:14.140]  Okay.
[28:29.030 --> 28:33.610]  If they ever get a recording contract, buy their album. We promise we'll give them a bargain.
[28:33.610 --> 28:34.370]  Yeah, we promise.
[28:34.370 --> 28:40.830]  Also, if you really like the song, I think there's a copy on your asterisk, not on your asterisk, on your Defcon CD.
[28:40.830 --> 28:48.550]  Also on your Defcon CD, there's the full copy of that song in every codec we just demonstrated, so you can listen to them and compare for yourself.
[28:48.550 --> 28:51.990]  We won't be responsible if you listen to the whole thing in LPC 10.
[28:52.370 --> 28:53.030]  Yeah.
[28:54.650 --> 29:00.090]  So let's talk about getting Asterisk to talk to the real phone network, because this is all fun and cool,
[29:00.090 --> 29:07.570]  but it's going to be kind of limited in use if you can't talk to, you know, your mobile phone or your mother or somebody on the street.
[29:09.030 --> 29:17.130]  There are various providers that, um, that you can use to terminate the public telephone network, and we're going to go into one of them.
[29:17.130 --> 29:22.190]  It's called Nuphone. Nuphone, uh, well, you know more about Nuphone than I do. Why don't you tell them?
[29:26.770 --> 29:35.010]  The plus about Nuphone is that they have cheap rates, not as cheap as some other voice-over ID providers, but pretty decent rates.
[29:35.410 --> 29:41.090]  They're very geared toward Asterisk. I believe they support this only under a nice public high-pride,
[29:41.090 --> 29:45.070]  saying, you know, I want to be assisted by, you know, a supporter or some other ADA.
[29:45.450 --> 29:51.710]  One of the things that I like about them, and at least my experience with my first provider, is that you can set your caller ID outcomes,
[29:51.710 --> 29:57.710]  which has some interesting, you know, applications to it. I'll cover that later.
[29:58.050 --> 30:04.310]  Um, and also the really cool thing about Nuphone, and I think it's their best feature, is they have insanely cheap provisioning.
[30:04.670 --> 30:10.930]  I never thought anywhere in my life I would ever have to find 800 numbers for my name, but I do.
[30:11.550 --> 30:15.490]  I, seriously, I click them and they send you an email saying, here's your 800 numbers.
[30:15.490 --> 30:23.230]  You can actually do vanity 800 numbers for them, like if we wanted to buy 800 Asterisks, I don't know how many characters it is.
[30:23.530 --> 30:25.510]  I've forgotten how many 800 numbers I own.
[30:25.510 --> 30:32.950]  Anyway, it takes a little longer for that, and they charge you a fee, but, you know, for any old 800 number that you want, it's just, you know, poof, it's yours.
[30:33.390 --> 30:39.110]  They're very easygoing. When I first set up my account with them, I'm not sure how they do that, but when I first set up my account with them,
[30:39.110 --> 30:44.750]  I said, oh, you know, we tell you, you know, we send you some money, what happens when that money's out, are you going to shut off my service?
[30:44.750 --> 30:49.690]  He said, no, we'll just send you a reminder email, you know, we'll just, you know, send it off.
[30:49.690 --> 30:52.450]  You won't turn off your service or anything, we'll just send you some money.
[30:53.610 --> 30:56.510]  They also have something called caller ID number for delivery.
[30:56.510 --> 31:00.430]  How many people are familiar with SS7 and the difference between CPN and CID?
[31:01.550 --> 31:02.750]  Oh, good amount of people do.
[31:02.790 --> 31:06.790]  Anyway, CPN is sort of like caller ID on steroids.
[31:08.170 --> 31:10.710]  It's a little more speedy than caller ID.
[31:10.710 --> 31:14.070]  You can actually do 9 times out of 10 unless you know what you're doing.
[31:14.130 --> 31:17.830]  CPN is usually very free-flow and you can't change it.
[31:18.150 --> 31:21.110]  Of course, you know, you're probably laughing at me.
[31:22.210 --> 31:26.730]  It's, caller ID on steroids is a little more free-flow and it's harder to mistake it, theoretically.
[31:27.430 --> 31:31.990]  They also have, quite recently, they have a blocker on deletion projects.
[31:31.990 --> 31:34.690]  Now, for the longest time, what would happen is, you know, like,
[31:34.690 --> 31:37.910]  your call would not go through or you'd get an intercept saying, like,
[31:37.910 --> 31:41.090]  the number you've been calling has been changed, so and so.
[31:41.090 --> 31:43.130]  It wouldn't actually work like that.
[31:43.930 --> 31:47.370]  And for someone like me, who's phone-free and enjoys calling intercepts,
[31:47.370 --> 31:49.690]  it was a bit of a bummer.
[31:49.990 --> 31:54.730]  But, you know, a couple weeks ago, oh, a couple months ago, by now,
[31:54.730 --> 31:56.030]  they actually turned it on.
[31:56.030 --> 32:04.650]  I called with a payphone out in Boston and I got, you know,
[32:04.650 --> 32:07.110]  I'm sorry, the phone number you've reached is not accepted.
[32:07.110 --> 32:10.170]  I literally picked up the phone and called him and said,
[32:10.170 --> 32:12.090]  who funds this proper conversation?
[32:12.090 --> 32:13.950]  And he was jumping out like a sleight of hand.
[32:13.950 --> 32:15.050]  He was too gross on the net.
[32:17.290 --> 32:19.630]  It was very exciting for me.
[32:20.710 --> 32:24.710]  CONSTED, directed for dial numbers, which are basically numbers you would call on,
[32:24.710 --> 32:28.710]  you would set up on the PSTN, so mom, dad, you know, your sister,
[32:28.710 --> 32:32.850]  someone who doesn't have an asterisk can call you and actually reach you on your woodline.
[32:32.850 --> 32:36.510]  The only numbers they have are in Michigan, which for me, I guess, is okay
[32:36.510 --> 32:39.290]  because no one really calls me on woodlines besides him.
[32:40.150 --> 32:44.030]  And they're also not too freak-friendly, despite being very easygoing.
[32:44.030 --> 32:51.330]  For example, during Strong and Lucky 55's presentation last year on freaking in the age of voice over IP,
[32:51.330 --> 32:51.590]  was it?
[32:51.590 --> 32:53.150]  Yeah, I think it was something like that.
[32:53.270 --> 32:57.690]  They sent them a cease and desist letter saying, no, they didn't send me a cease and desist letter.
[32:57.730 --> 32:59.590]  Who did they send a cease and desist letter?
[32:59.590 --> 33:01.490]  Was it not there yet?
[33:01.570 --> 33:02.950]  It's not there yet. Stand up.
[33:03.770 --> 33:05.110]  Here's Mr. Cease and Desist.
[33:05.110 --> 33:11.670]  This is the man who's on Jeremy McNamara's shit list.
[33:11.670 --> 33:17.130]  He basically said, you know, if you do this, I will terminate your account and ban you for life from New Phone.
[33:19.230 --> 33:20.870]  I haven't heard a peep out of him.
[33:21.670 --> 33:23.270]  Okay, we're just going to...
[33:24.270 --> 33:26.290]  Oh, they stopped carrying CPM this week.
[33:27.370 --> 33:28.230]  Oh, great.
[33:28.230 --> 33:31.750]  This is what we did.
[33:42.560 --> 33:45.320]  We used to like Astrolink until this weekend.
[33:49.220 --> 33:57.840]  Astrolink, for the most part, for me, has been reliable, although this week has been a whole other bag of forms which we'll get into later.
[33:58.380 --> 34:02.700]  You can get your inbound termination via toll-free numbers.
[34:02.700 --> 34:06.640]  And, of course, AMI-II. How many of you do not know what AMI-II is?
[34:08.500 --> 34:10.860]  AMI-II is the class of service.
[34:10.860 --> 34:17.880]  So you can tell whether your calls are coming in from an AMI phone or a mobile phone or a pay phone, what type of pay phone.
[34:17.880 --> 34:20.340]  You can see whether your calls are coming in from a person or two.
[34:21.600 --> 34:24.220]  And Astrolink does also proper call completion.
[34:24.480 --> 34:30.020]  So if you get the PPM at the port and your numbers have changed, you can do that.
[34:30.020 --> 34:33.860]  The con of the AMI-II interface is that it's a little bit clunky.
[34:35.280 --> 34:40.560]  It's actually gotten better. I was actually able to use it with Firefox for the first time this week.
[34:40.740 --> 34:45.060]  But I had to try it for a while, so it didn't quite work right with Firefox.
[34:46.140 --> 34:52.200]  And right now, at least, they're experiencing each two different problems with some customers, namely us.
[34:53.360 --> 34:55.160]  This is why we don't like them anymore.
[34:55.160 --> 35:00.000]  But we'll get into our beef with Astrolink later.
[35:00.860 --> 35:04.900]  There's also Voice Calls Connect, which I use to do my inbound calls.
[35:05.120 --> 35:08.120]  They give you a local numbering in almost every center you want.
[35:08.120 --> 35:11.280]  You get unlimited internet minutes on inbound EECS calls.
[35:11.620 --> 35:14.340]  And you have inbound numbers for a large number of great centers.
[35:14.340 --> 35:16.160]  And it's also called a proper call program.
[35:16.160 --> 35:22.580]  The problem is, it's one of the most expensive EECS providers for outbound information.
[35:23.800 --> 35:26.220]  New Phone is about two cents a minute.
[35:26.280 --> 35:28.360]  Astrolink is also two cents a minute.
[35:28.360 --> 35:32.840]  Voice Calls Connect is, I think, it used to be 2.9 cents a minute.
[35:32.840 --> 35:37.420]  Then they dropped it down to the low, low price of 2.4 cents a minute or something like that.
[35:37.420 --> 35:38.500]  Wow, that's not ideal.
[35:40.820 --> 35:46.180]  I guess when you go landline long distance, it's five cents a minute, like my inbound call.
[35:46.180 --> 35:47.540]  There's something else you can totally keep.
[35:47.540 --> 35:51.880]  When you've got providers that do 1.3 cents a minute, you're getting better.
[35:54.100 --> 35:57.240]  And the other thing is that inbound numbers with Voice Calls Connect,
[35:59.500 --> 36:02.900]  my number that's on my business card is a Voice Calls Connect number.
[36:02.900 --> 36:07.860]  And for some reason, usually I have to go to a menu.
[36:07.860 --> 36:09.280]  You know, thank you for calling for strong cards.
[36:09.280 --> 36:10.480]  My PBX is strong.
[36:10.480 --> 36:11.300]  I like to be clear.
[36:11.300 --> 36:13.180]  I like to show you that I appreciate what you're doing.
[36:15.220 --> 36:19.360]  And I had someone trying to call me, and they kept pressing 2, and it would just hang up on them.
[36:19.360 --> 36:21.800]  Because my PBX never heard the 2.
[36:21.920 --> 36:26.700]  So I had to make a move directly to my mobile phone this weekend.
[36:27.880 --> 36:29.140]  Apparently, this is the first sentence.
[36:29.140 --> 36:32.380]  This is the first sentence that happened to me, but some people are having major issues with it.
[36:32.380 --> 36:35.160]  So if you're really unlucky, you're totally screwed.
[36:36.740 --> 36:37.560]  Here's VoiceJet.
[36:37.560 --> 36:38.400]  It's really cheap.
[36:38.400 --> 36:39.800]  It's 1.3 cents a minute.
[36:41.840 --> 36:45.020]  Actually, I think it's 1.29 now.
[36:45.200 --> 36:45.680]  Oh, is it?
[36:45.680 --> 36:46.240]  Wow.
[36:46.520 --> 36:48.420]  A whole mil when they dropped it.
[36:49.020 --> 36:50.200]  Hey, it adds up.
[36:50.200 --> 36:50.760]  Yeah, it does.
[36:50.760 --> 36:51.320]  It does.
[36:51.720 --> 36:54.180]  Caller ID delivery is unreliable with VoiceJet.
[36:54.180 --> 36:58.700]  You oftentimes get the number where I found the call, instead of the number that you set it to.
[36:58.840 --> 37:02.880]  There's no e-mail service that's appropriate, and there's no proper call completion.
[37:02.880 --> 37:08.300]  If you call a number that's been disconnected, and the phone company that you're giving it to says,
[37:08.300 --> 37:12.360]  this number has been disconnected, all you'll hear is the phone ringing and ringing and ringing.
[37:12.640 --> 37:18.320]  So you'll never know why your mother has changed her phone number in your situation.
[37:19.820 --> 37:21.540]  She doesn't love me!
[37:24.740 --> 37:25.740]  Exactly, see?
[37:26.500 --> 37:28.860]  It's because we all use LPCs now.
[37:29.860 --> 37:31.880]  There's also a company called Broadvoice.
[37:32.200 --> 37:34.600]  They have cheap PIDs in most race centers.
[37:42.340 --> 37:44.140]  They're pretty much run by phone freaks.
[37:44.140 --> 37:49.860]  In fact, when you sign up, you have them send you the kit with the ATA and everything.
[37:49.860 --> 37:53.860]  They also send you this little pin, which is this logo,
[37:53.860 --> 37:56.500]  with the red circle and the slash through it.
[37:56.660 --> 38:00.020]  I actually found out this weekend they also do T-shirts.
[38:00.200 --> 38:04.240]  Yes, at least one person here at DEF CON is walking around with a Broadvoice pin,
[38:04.240 --> 38:06.960]  with the Bell logo and the slash through it.
[38:06.980 --> 38:10.400]  So if you hear that person, please stand up and get some T-shirts.
[38:11.760 --> 38:13.260]  He's not here? What the hell?
[38:13.260 --> 38:14.180]  They lose.
[38:14.440 --> 38:15.340]  You lose.
[38:15.720 --> 38:17.920]  We were going to give you just like $100,000.
[38:18.700 --> 38:20.600]  They were going to get the payphone, too.
[38:22.220 --> 38:27.200]  Oh, and the other cool thing is that you get a caller ID with name for inbound calls.
[38:27.200 --> 38:29.620]  Most of these other carriers will just deliver the number,
[38:29.620 --> 38:33.400]  but these people will actually do a name level and deliver the name for you.
[38:33.400 --> 38:38.060]  So we'll see not just that 311-555-2368 is calling you,
[38:38.060 --> 38:40.860]  but that it's from Mabel's fish restaurant or something.
[38:41.260 --> 38:43.280]  The problem is that it's SIF only.
[38:43.320 --> 38:46.940]  So if you want to do EECS termination or if you're trying to firewall or something,
[38:46.940 --> 38:48.700]  you've got to do some sort of EECS proxy
[38:48.700 --> 38:50.960]  if you want it to be reliable.
[38:51.360 --> 38:53.160]  They're prone to service outages.
[38:53.340 --> 38:57.040]  I've got, you know, my dial type is the 1-plus-8-4-7 number.
[38:57.040 --> 38:58.340]  It just goes over broad voice.
[39:02.120 --> 39:03.960]  But sometimes those things can work.
[39:04.360 --> 39:06.980]  Phone support is kind of slow, although it is 24-7.
[39:06.980 --> 39:10.520]  So I guess if you call at, you know, 3 a.m., they will answer like that.
[39:10.760 --> 39:12.000]  No, they won't.
[39:13.400 --> 39:14.340]  Yeah, I try.
[39:14.340 --> 39:15.540]  They'll have to wake up first.
[39:15.540 --> 39:17.600]  Then they'll, you know, drink their coffee.
[39:18.700 --> 39:21.520]  And then the other thing is CNN delivery is also unreliable.
[39:21.520 --> 39:25.560]  So, you know, caller ID name tends to work, but it doesn't work all the time.
[39:26.740 --> 39:30.500]  So now let's get into building your asterisk network.
[39:31.680 --> 39:33.940]  Why don't you explain enum, Ben?
[39:34.020 --> 39:41.400]  Okay, Brandon.
[39:44.510 --> 39:52.470]  Enum was the first way to actually translate code numbers over to URLs in SIF.
[39:52.470 --> 39:54.270]  It's based on DNS.
[39:54.550 --> 39:56.330]  It allows you to read numbers and query.
[39:56.450 --> 40:01.730]  And what it does is it basically bypasses the public switch telephone network.
[40:02.290 --> 40:06.670]  So, you know, I know that 3-1-1-5-5-5-2-3-6-8 is a voice number.
[40:06.670 --> 40:07.470]  How can I do that?
[40:07.470 --> 40:08.090]  I don't know.
[40:08.990 --> 40:15.390]  So the type I can use is supposed to be used by telecom companies.
[40:15.390 --> 40:17.450]  However, there's a program out there.
[40:17.510 --> 40:18.730]  I think this is the largest one.
[40:18.730 --> 40:19.730]  I may be wrong.
[40:19.750 --> 40:22.050]  It's called 2-1-2-3-4.org.
[40:22.050 --> 40:24.010]  It's a free do-it-yourself solution.
[40:24.010 --> 40:28.810]  What you do is you register your number in 2-1-2-3-4-5-5-2-3-6-8,
[40:28.810 --> 40:30.610]  and you register it to a URL.
[40:30.610 --> 40:37.410]  And then someone queries their enum server, then, over the Internet.
[40:42.720 --> 40:49.950]  But then you realize that local exchanges can't access 2-1-1-5 numbers,
[40:49.950 --> 40:53.590]  and how many exchanges you've got can't access 2-1-2-3-4-5-6-8.
[40:53.670 --> 40:56.410]  I think in an area code, there's a maximum limit.
[40:56.410 --> 40:59.370]  We've always reserved 3-1-2-3-4-7-2-2 million numbers.
[40:59.370 --> 41:01.710]  And Los Angeles has how many area codes now?
[41:02.070 --> 41:03.610]  So, a lot.
[41:03.710 --> 41:08.730]  They also have 78 million special PSTN services.
[41:08.730 --> 41:10.330]  So you're essentially...
[41:10.330 --> 41:13.550]  you can offer free termination of $800,
[41:13.550 --> 41:20.500]  which is basically a PSTN termination service.
[41:20.500 --> 41:22.700]  You can use this, and you can dial in your numbers.
[41:25.340 --> 41:27.200]  How e-mail works...
[41:28.060 --> 41:29.460]  I left it in my car.
[41:31.720 --> 41:32.580]  Everything's in my car.
[41:32.580 --> 41:34.400]  Okay, if we all pay attention to the top,
[41:34.400 --> 41:36.060]  basically, I'm at the top of my phone,
[41:36.060 --> 41:39.300]  and I want to dial 3-1-1-5-5-5-2-3-6-8.
[41:40.080 --> 41:40.820]  Oh, yeah.
[41:42.240 --> 41:44.260]  Touchpad, marvels of modern technology.
[41:44.260 --> 41:45.640]  Yes, latest thing in Virginia.
[41:46.460 --> 41:47.440]  I'm at this telephone.
[41:47.440 --> 41:50.100]  I basically want to dial 3-1-1-5-5-5-2-3-6-8.
[41:50.100 --> 41:51.840]  So I pick up my handset, dial it,
[41:51.840 --> 41:53.040]  and talk to my DVX.
[41:53.040 --> 41:56.320]  It says, okay, I want to dial 3-1-1-5-5-5-2-3-6-8.
[41:56.320 --> 41:57.460]  Connect me there somehow.
[41:57.460 --> 41:59.120]  So what I set up my DVX to do
[41:59.120 --> 42:00.500]  is talk to a medium circle.
[42:00.960 --> 42:02.540]  And it says, hey, do you know
[42:02.540 --> 42:05.100]  what 3-1-1-5-5-5-2-3-6-8 is?
[42:05.320 --> 42:07.440]  And it says, yes or no.
[42:07.440 --> 42:08.540]  And essentially, in this example,
[42:08.540 --> 42:10.660]  it says, yes, it's a bell at telephone.com.
[42:10.660 --> 42:12.280]  So it registers that to my DVX,
[42:12.280 --> 42:14.740]  at which point my DVX goes,
[42:14.740 --> 42:17.340]  ooh, I guess I'll go over to the internet.com
[42:17.340 --> 42:19.020]  rather than picking up a local line.
[42:19.020 --> 42:19.980]  And it goes over the internet,
[42:19.980 --> 42:22.140]  and I dial 3-1-1-5-5-5-2-3-6-8
[42:22.140 --> 42:23.100]  down here, which they also
[42:23.100 --> 42:24.980]  don't do at 3-1-1-5-5-5-2-3-6-8.
[42:24.980 --> 42:27.480]  They're also completely bypassing the BSDN.
[42:28.780 --> 42:30.260]  Email is a very...
[42:30.260 --> 42:32.300]  has a lot of problems in my opinion.
[42:32.300 --> 42:33.620]  It's a very top-down way
[42:33.620 --> 42:34.900]  of looking at things.
[42:34.900 --> 42:36.900]  It's centrally managed, centrally served,
[42:36.900 --> 42:37.920]  and centrally centralized.
[42:37.920 --> 42:40.720]  Basically, they wanted developers
[42:40.720 --> 42:42.560]  exactly like DNS and have, you know,
[42:42.560 --> 42:44.680]  15 root servers all over the world,
[42:44.680 --> 42:46.260]  which is great, but no one actually
[42:46.260 --> 42:47.420]  has done it yet.
[42:49.960 --> 42:52.040]  And it's not being used
[42:52.040 --> 42:54.440]  by any BSDN developers.
[42:54.520 --> 42:55.680]  As far as we know.
[42:56.300 --> 42:58.420]  Does someone want to tell me otherwise?
[43:00.800 --> 43:02.140]  My idea is how
[43:02.140 --> 43:03.940]  logically they save you money, you know.
[43:03.940 --> 43:05.220]  I can charge you 5 cents a minute
[43:05.220 --> 43:06.740]  for, you know,
[43:08.400 --> 43:09.900]  and it's nowhere near
[43:09.900 --> 43:10.940]  where it would last.
[43:11.300 --> 43:13.420]  We're working towards a really nice solution
[43:13.420 --> 43:16.140]  that's starting to get there, but at the same point,
[43:16.140 --> 43:17.820]  you know...
[43:28.880 --> 43:30.240]  Something like that, yeah.
[43:30.240 --> 43:31.080]  So last April,
[43:31.080 --> 43:32.160]  what someone set out with
[43:45.290 --> 43:46.630]  is a fully peer-to-peer
[43:46.630 --> 43:48.110]  E164 solution.
[43:48.110 --> 43:48.270]  It's a fully peer-to-peer
[43:48.270 --> 43:48.330]  E164 solution.
[43:48.330 --> 43:48.850]  Basically, you know,
[43:48.850 --> 43:57.740]  it sets up your own
[43:57.740 --> 43:58.900]  telephone network for fresh
[43:58.900 --> 44:05.410]  for your telephone company.
[44:05.410 --> 44:07.670]  You know,
[44:22.380 --> 44:24.200]  5, 5, 5, 1, 2, 3, 4.
[44:26.640 --> 44:27.240]  So,
[44:27.240 --> 44:28.380]  we've got this DBS here,
[44:28.380 --> 44:30.080]  and it talks to this node over here,
[44:30.080 --> 44:31.220]  and what this node does,
[44:31.220 --> 44:32.040]  it only has one node,
[44:33.060 --> 44:37.320]  and what it does is
[44:37.320 --> 44:38.200]  it reaches that node,
[44:38.200 --> 44:39.720]  and that node talks to only this one,
[44:41.800 --> 44:43.360]  and it reaches the DBS node,
[44:43.360 --> 44:43.960]  it's got a dial,
[44:43.960 --> 44:47.480]  3, 5, 5, 2, 5, 6,
[44:47.480 --> 44:48.340]  at which point,
[44:48.340 --> 44:50.100]  it scrolls back and says,
[44:50.100 --> 44:54.510]  hey, 411 service,
[44:57.270 --> 44:58.710]  this is all it.
[45:03.480 --> 45:04.120]  Basically,
[45:04.120 --> 45:04.860]  it's a very good
[45:04.860 --> 45:06.260]  peer-to-peer setup,
[45:06.260 --> 45:11.320]  which has some problems with
[45:11.320 --> 45:12.800]  Dundee, in my opinion, also.
[45:13.040 --> 45:15.100]  To be honest, I mean,
[45:15.100 --> 45:16.360]  essentially, what I could start doing
[45:16.360 --> 45:17.880]  is I could start advertising, hey,
[45:17.880 --> 45:19.040]  all the numbers to the White House,
[45:19.040 --> 45:20.100]  send them to me,
[45:20.100 --> 45:21.280]  so I can, you know,
[45:21.280 --> 45:22.900]  start World War III,
[45:25.340 --> 45:26.140]  scalability,
[45:28.520 --> 45:30.140]  we're not sure how it's going to be
[45:30.140 --> 45:33.120]  still relatively small,
[45:33.120 --> 45:34.500]  but I've never seen a product
[45:34.500 --> 45:36.600]  like Nutella.
[45:36.600 --> 45:38.340]  Look how many problems we had with that.
[45:38.820 --> 45:40.520]  It's not officially a standard yet,
[45:40.520 --> 45:42.460]  we just submitted it to IETF,
[45:42.460 --> 45:44.780]  but as we all know, standards cost money,
[45:44.780 --> 45:46.960]  and these people don't have it.
[45:48.080 --> 45:49.540]  Right now, it's only officially
[45:49.540 --> 45:50.520]  in DBS,
[45:50.520 --> 45:53.640]  and we can submit it,
[45:59.810 --> 46:01.350]  and run it against 109,
[46:01.350 --> 46:02.750]  or 107, or whatever,
[46:02.750 --> 46:04.610]  and get some support in it,
[46:04.610 --> 46:05.450]  and in my opinion,
[46:05.450 --> 46:06.630]  it works fine,
[46:06.630 --> 46:07.650]  and also in my opinion,
[46:07.650 --> 46:08.450]  I think the eye of the beholder
[46:08.450 --> 46:10.850]  should be nice.
[46:14.600 --> 46:15.700]  Quality assurance,
[46:15.700 --> 46:23.500]  what quality assurance
[46:23.500 --> 46:24.120]  do you charge
[46:24.120 --> 46:26.140]  for your
[46:26.140 --> 46:28.240]  for your phone call
[46:28.240 --> 46:29.840]  going out over your WAN,
[46:29.840 --> 46:31.320]  for example,
[46:31.320 --> 46:32.380]  I don't have quality assurance
[46:32.380 --> 46:33.660]  for my WAN,
[46:33.660 --> 46:39.020]  or for example,
[46:39.020 --> 46:39.660]  for my WAN.
[46:41.620 --> 46:42.900]  There's two ways of doing it.
[46:42.900 --> 46:43.720]  Can we do this?
[46:45.340 --> 46:47.160]  No, no.
[46:47.500 --> 46:48.760]  Okay, we'll do it that way.
[46:51.670 --> 46:52.770]  Sorry, I forgot to dial
[46:52.770 --> 46:54.370]  something in my PBX earlier.
[46:55.730 --> 46:56.870]  Basically, there are two ways
[46:56.870 --> 46:58.050]  you can use QoS here.
[46:58.050 --> 46:58.830]  There's priority QoS,
[46:58.830 --> 46:59.750]  which can give you a way back
[46:59.750 --> 47:00.890]  to priority over any other
[47:00.890 --> 47:01.470]  factor,
[47:02.150 --> 47:06.610]  where you can basically
[47:07.110 --> 47:08.290]  reserve your WAN
[47:08.290 --> 47:09.270]  and turn it away
[47:09.270 --> 47:12.090]  and get the rest of it for it.
[47:12.090 --> 47:13.890]  But for everything that's not QoS,
[47:13.890 --> 47:15.730]  you get the rest of the WAN.
[47:16.750 --> 47:18.630]  I'm sure there's more
[47:18.630 --> 47:20.170]  about that, but I'm a phone person,
[47:20.170 --> 47:21.210]  not a router person.
[47:21.570 --> 47:23.770]  Many residential routers are now voice aware
[47:23.770 --> 47:25.970]  and will do the sort of thing right out of the box.
[47:26.490 --> 47:27.730]  And you can also
[47:27.730 --> 47:30.190]  if you're a control freak,
[47:30.190 --> 47:31.610]  or if you want to do it on a larger scale,
[47:31.610 --> 47:34.610]  then you can connect your router
[47:36.560 --> 47:37.900]  and say, hey, I've got a super router phone
[47:37.900 --> 47:39.640]  and I've sort of gotten working
[47:39.640 --> 47:42.040]  and I'm definitely not a super router person.
[47:42.920 --> 47:44.560]  So now let's get into the
[47:44.560 --> 47:46.860]  cool part of what you can do
[47:46.860 --> 47:47.620]  with Asterisk.
[47:47.660 --> 47:50.200]  And by the way, if you're watching on TV
[47:50.200 --> 47:51.340]  in the hotel,
[47:52.080 --> 47:54.260]  we've got a special thing coming up for you.
[47:56.580 --> 47:58.040]  Asterisk Gateway Interface.
[47:58.080 --> 47:59.300]  Do you want to talk about that?
[48:03.360 --> 48:04.900]  Experts on certain subjects?
[48:06.640 --> 48:08.040]  Yes, Tag Team, exactly.
[48:09.820 --> 48:15.660]  So,
[48:15.660 --> 48:16.540]  Asterisk Gateway Interface.
[48:16.540 --> 48:18.380]  What it is, is an interface for adding
[48:19.460 --> 48:20.680]  functionality to Asterisk.
[48:20.680 --> 48:23.000]  It basically uses standard in and standard out.
[48:23.000 --> 48:24.280]  And it's very cross-language.
[48:24.280 --> 48:26.920]  You infer, you see, you PHP,
[48:27.240 --> 48:28.620]  Lisp, PCL,
[48:28.620 --> 48:30.640]  anything that uses standard in and standard out,
[48:30.640 --> 48:32.180]  you can use it.
[48:32.600 --> 48:34.800]  And basically, since Asterisk is the best thing
[48:34.800 --> 48:37.040]  since sliced bread, I find AGI to be the best thing
[48:37.040 --> 48:37.980]  since sliced bread.
[48:38.500 --> 48:40.780]  Because you can basically do anything you want with it
[48:40.780 --> 48:41.960]  given enough time.
[48:42.440 --> 48:44.420]  Here's a simple AGI for a minute.
[48:44.420 --> 48:45.140]  Wow!
[48:46.100 --> 48:47.540]  What it is, is basically,
[48:47.540 --> 48:50.580]  I don't know if you can actually see it
[48:50.580 --> 48:52.180]  up on the screen, I apologize.
[48:52.960 --> 48:54.340]  What it does, is basically...
[48:54.340 --> 48:55.780]  It's not in your Dendy notebook?
[48:57.840 --> 48:58.960]  Oh, great.
[49:00.020 --> 49:00.560]  This is what
[49:00.560 --> 49:01.720]  apparently electricity parts
[49:01.720 --> 49:02.720]  don't work.
[49:04.240 --> 49:06.240]  So, basically,
[49:06.360 --> 49:07.760]  a lot of my presentation of this part
[49:07.760 --> 49:08.760]  hasn't been done.
[49:11.260 --> 49:12.120]  Starting from here,
[49:12.120 --> 49:13.080]  basically, what it is, is
[49:15.300 --> 49:16.680]  start on a standard in point,
[49:16.680 --> 49:17.900]  standard in and standard out.
[49:17.900 --> 49:18.980]  Basically, what Asterisk does is
[49:18.980 --> 49:23.340]  it reads all the variables in
[49:23.340 --> 49:25.100]  and checks all of it.
[49:25.100 --> 49:27.320]  It checks to make sure, 200 times per day,
[49:27.320 --> 49:28.300]  5 times per day,
[49:28.300 --> 49:30.720]  that we're not sure about the quality
[49:30.720 --> 49:32.700]  and it means that
[49:32.700 --> 49:36.780]  you just keep on going.
[49:38.400 --> 49:39.620]  Basically, what happens is
[49:39.620 --> 49:40.920]  after you read all the variables in
[49:40.920 --> 49:42.620]  and make sure they're OK,
[49:42.620 --> 49:44.820]  what it does is, it streams a file
[49:44.820 --> 49:47.600]  that says, your caller ID is...
[49:47.600 --> 49:49.700]  and it says,
[49:49.700 --> 49:51.220]  you recheck your caller ID.
[49:51.560 --> 49:53.400]  So, here's how it works.
[49:53.680 --> 49:54.900]  I've backed up here,
[49:54.900 --> 50:03.630]  but the one we're really interested in
[50:03.630 --> 50:07.270]  is AGI caller ID, which says 311-555-2368.
[50:07.470 --> 50:08.450]  And then it says,
[50:08.450 --> 50:09.810]  after it's done feeding all the variables,
[50:09.810 --> 50:10.950]  it says 200 results here,
[50:10.950 --> 50:12.830]  it means I'm done in 41 minutes.
[50:12.830 --> 50:14.470]  It says, OK, stream file,
[50:14.470 --> 50:16.470]  you know, AGI caller ID.
[50:19.790 --> 50:20.790]  Then it says,
[50:20.790 --> 50:22.250]  OK, I'm done, what do you want me to do?
[50:22.410 --> 50:23.770]  OK, stream pages,
[50:23.770 --> 50:25.830]  311-555-2368,
[50:26.950 --> 50:28.890]  AGI command that asterisk understands,
[50:29.390 --> 50:30.810]  and it goes,
[50:30.810 --> 50:32.530]  you know, says 3, 1, 1,
[50:35.720 --> 50:36.780]  200 results here,
[50:36.780 --> 50:38.760]  OK, I'm done. And at which point it says,
[50:38.760 --> 50:40.400]  hang up, I'm done.
[50:41.500 --> 50:42.760]  It takes it back to me,
[50:42.760 --> 50:44.700]  sends back, you know, 200 results here,
[50:44.700 --> 50:46.240]  I'm done now, it hangs up.
[50:50.060 --> 50:50.880]  Yes, exactly,
[50:50.880 --> 50:53.180]  AGI caller ID readback, ENAC.
[50:56.620 --> 50:57.420]  Now,
[50:57.420 --> 50:59.120]  that's a lot of work to do
[50:59.120 --> 51:04.210]  in what's called asterisk AGI,
[51:04.210 --> 51:06.370]  which is a Perl module for asterisk
[51:06.370 --> 51:07.950]  in writing AGI scripts.
[51:08.270 --> 51:10.590]  It simplifies a lot of AGI programming.
[51:10.590 --> 51:12.090]  Essentially, it takes out a lot of the dirty work
[51:12.090 --> 51:14.270]  and takes away everyone's doing the work
[51:14.270 --> 51:15.450]  that you don't have to.
[51:15.450 --> 51:17.590]  It allows the AGI to control
[51:17.590 --> 51:19.950]  the simple object interface in Perl.
[51:20.210 --> 51:23.530]  The problem is,
[51:23.530 --> 51:25.830]  I subscribed to the mailing list
[51:26.050 --> 51:27.630]  a few months ago,
[51:27.630 --> 51:28.890]  and it's been dead silent
[51:28.890 --> 51:30.170]  for the last few months ago,
[51:30.170 --> 51:30.910]  and someone said,
[51:30.910 --> 51:32.430]  is this mailing list still active?
[51:32.550 --> 51:33.410]  At which point I'm going to be
[51:33.410 --> 51:34.650]  not able to work anymore.
[51:34.870 --> 51:38.010]  Maybe I should set up another thing,
[51:38.010 --> 51:38.710]  or maybe a few people
[51:38.710 --> 51:39.610]  should sign up to it
[51:39.610 --> 51:41.870]  and start using it yourselves.
[51:42.410 --> 51:43.490]  What it is, is it allows
[51:43.490 --> 51:45.630]  the AGI to easily integrate with Perl,
[51:45.630 --> 51:47.730]  which easily integrates
[51:47.730 --> 51:50.150]  with almost anything in the known universe.
[51:50.230 --> 51:51.130]  And it's available at
[51:51.130 --> 51:52.730]  asterisk.uniter.net
[51:53.290 --> 51:55.910]  which is a very strange German word
[51:55.910 --> 51:59.910]  for like the longest time.
[52:00.230 --> 52:01.610]  Here's the same program.
[52:01.650 --> 52:03.770]  As you can tell, it gets a lot easier.
[52:03.770 --> 52:05.470]  I think we can test this out at least 100%
[52:05.470 --> 52:07.490]  to about 10 lines or so.
[52:07.590 --> 52:10.230]  So this is, you know,
[52:10.230 --> 52:11.370]  it reads in, you know,
[52:11.370 --> 52:14.030]  starts up a new object
[52:14.030 --> 52:15.070]  called AGI.
[52:15.270 --> 52:17.370]  You know that entire, you know,
[52:18.090 --> 52:20.070]  10 line thing, check the variables,
[52:20.070 --> 52:21.050]  make sure they're okay.
[52:21.070 --> 52:22.210]  It does it all automatically.
[52:23.710 --> 52:25.670]  And the other feature that the other
[52:25.670 --> 52:28.050]  one didn't have is you did not check
[52:28.050 --> 52:29.590]  whether or not the person had a caller ID
[52:29.590 --> 52:30.690]  in the first place.
[52:31.250 --> 52:33.170]  So you basically, if you didn't have a caller ID,
[52:33.170 --> 52:34.350]  you did a file file saying,
[52:34.350 --> 52:36.410]  the caller ID is, and then it would hang up.
[52:36.410 --> 52:38.090]  Or what this one does is it checks
[52:38.090 --> 52:42.290]  to see if your caller ID is, you know,
[52:42.290 --> 52:43.970]  what this would do if you didn't have a caller ID,
[52:43.970 --> 52:45.790]  it would just hang up on you.
[52:46.010 --> 52:48.310]  And as I say, wow, it's easier to do.
[52:48.750 --> 52:53.280]  It checks to see if your caller ID
[52:54.000 --> 52:55.380]  is on touch-tone.
[52:55.900 --> 52:58.600]  Basically, everyone knows how to use it,
[52:58.600 --> 52:59.700]  including your mom.
[53:00.360 --> 53:01.920]  However, you know, it's very limited
[53:01.920 --> 53:02.900]  on what you can do with it.
[53:02.900 --> 53:04.760]  For example, you have to use the sign-up function
[53:05.160 --> 53:07.280]  to use it, or, you know,
[53:07.280 --> 53:09.200]  you can only use it if you have five members.
[53:09.200 --> 53:17.970]  The XML, it's extensible.
[53:18.570 --> 53:19.690]  WebPXML is extensible.
[53:19.690 --> 53:21.810]  VoiceXML is basically an XML
[53:21.810 --> 53:24.090]  that allows for scripting
[53:24.090 --> 53:25.650]  with a voice interface.
[53:25.650 --> 53:26.450]  It's extensible.
[53:26.450 --> 53:28.230]  The problem with Asterisk is that it has no
[53:28.230 --> 53:35.900]  relatively new open-source program
[53:35.900 --> 53:37.660]  called Asterisk PDF, which says
[53:37.660 --> 53:42.240]  it has Asterisk CIFS.
[53:43.040 --> 53:45.040]  So I spent about two weeks
[53:45.040 --> 53:46.220]  trying to get this compiled.
[53:46.220 --> 53:47.800]  It's a high-resolution
[53:47.800 --> 53:48.800]  demonstration.
[53:48.800 --> 53:49.800]  There's also
[53:49.800 --> 53:52.240]  commercial offerings. For example, Microsoft
[53:52.240 --> 53:53.740]  has a new VXML program
[53:54.420 --> 53:59.850]  where there's, like, at least two or three
[53:59.850 --> 54:01.890]  commercial ones that I know of that
[54:01.890 --> 54:04.150]  are also free
[54:04.150 --> 54:05.150]  open-source.
[54:05.650 --> 54:07.170]  VXML is still, you know,
[54:07.170 --> 54:13.460]  you need to use.
[54:31.420 --> 54:32.420]  Think back
[54:32.420 --> 54:34.000]  to that Texas speech program you played with
[54:34.000 --> 54:35.640]  in, like, 1987.
[54:37.020 --> 54:41.120]  That program is called
[54:41.120 --> 54:41.900]  Cepstral.
[54:41.900 --> 54:47.520]  Cepstral is a free
[54:47.520 --> 54:48.380]  free-for-download
[54:49.540 --> 54:51.000]  free-for-download program
[54:51.000 --> 54:52.620]  that they've also announced
[55:09.530 --> 55:11.450]  however it's not free.
[55:24.260 --> 55:25.580]  Something like that.
[55:25.740 --> 55:27.840]  You can play with a
[55:27.840 --> 55:29.660]  free version of Cepstral, but
[55:30.180 --> 55:31.580]  it's also a sound file
[55:31.580 --> 55:34.620]  and every fifth or tenth word or something goes
[55:34.620 --> 55:36.900]  please register me.
[55:36.900 --> 55:38.020]  Yeah, and it is free
[55:38.020 --> 55:39.880]  for download, like you said, and you can make sure
[55:39.880 --> 55:41.340]  if you ever have, like, you know, one of the programs
[55:41.340 --> 55:42.740]  and you want to make sure that it works with your program
[55:42.740 --> 55:44.940]  you can set it up and, you know, you just have to do
[55:44.940 --> 55:46.660]  that please register me every time it works
[55:46.660 --> 55:47.860]  or something.
[55:49.360 --> 55:50.600]  The other thing for output is
[55:50.600 --> 55:53.440]  reports. You can get your stuff for free.
[55:54.040 --> 55:55.140]  The other person is Allison
[55:55.140 --> 55:56.980]  and she has huge support
[55:56.980 --> 55:58.400]  for Asterisk.
[55:58.820 --> 56:01.020]  It's for pay and she has lots of
[56:01.020 --> 56:02.740]  fan sayings available on the internet.
[56:02.960 --> 56:05.340]  Asterisk also comes with a whole ton of sayings
[56:05.340 --> 56:07.420]  and she says all sorts of crazy stuff
[56:07.420 --> 56:08.240]  in the LA area.
[56:17.760 --> 56:19.520]  A friend of mine actually
[56:19.520 --> 56:21.440]  just wanted to test her
[56:21.440 --> 56:22.640]  and so he sent her
[56:22.640 --> 56:24.820]  increasingly offensive scripts
[56:24.820 --> 56:27.140]  and I think he finally found her
[56:27.260 --> 56:28.920]  a little bit after...
[56:28.920 --> 56:31.060]  yeah, a long time.
[56:33.100 --> 56:34.040]  Well, maybe she'll read
[56:34.040 --> 56:35.400]  Richard Nixon's Social Security number,
[56:35.400 --> 56:36.180]  I don't know.
[56:37.440 --> 56:44.860]  Basically,
[56:44.860 --> 56:45.740]  we have a...
[56:57.110 --> 56:58.050]  I'm not a weather
[56:58.050 --> 56:59.810]  fan, my name is Ron.
[57:01.870 --> 57:02.790]  Phone!
[57:03.630 --> 57:04.410]  I'll show you
[57:04.410 --> 57:05.990]  my phone voice in a second.
[57:37.730 --> 57:38.010]  And now
[57:38.130 --> 57:39.490]  a demonstration by Scott Carlson
[57:39.490 --> 57:40.410]  that we actually do.
[57:40.670 --> 57:43.830]  Good afternoon.
[57:43.830 --> 57:46.110]  Thank you for calling DEF CON My Phone.
[57:46.110 --> 57:47.270]  Script getting tested,
[57:47.270 --> 57:48.550]  Blamer approved.
[57:49.650 --> 57:51.630]  To hear what's coming up in the next hour,
[57:51.630 --> 57:53.630]  press 1. To search for an event,
[57:53.630 --> 57:55.570]  press 2. To need feedback from
[57:55.570 --> 57:57.970]  DEF CON My Phone team, press 0.
[57:59.010 --> 58:00.230]  And so on.
[58:04.530 --> 58:05.750]  If any of you
[58:05.750 --> 58:07.650]  want to write down silly things on slips of
[58:07.650 --> 58:08.350]  paper and
[58:09.430 --> 58:10.710]  leave them up here,
[58:10.710 --> 58:11.770]  I'll do them for you.
[58:11.770 --> 58:17.350]  Here's a slightly more complex
[58:17.350 --> 58:18.310]  thing, this actually uses
[58:18.310 --> 58:19.690]  input and output.
[58:20.150 --> 58:21.150]  Basically, what it does is
[58:21.150 --> 58:23.330]  I've got three ways of doing it.
[58:23.330 --> 58:24.310]  One of those is
[58:24.310 --> 58:27.250]  using CGI, and basically
[58:27.250 --> 58:28.210]  it lets you forever
[58:29.450 --> 58:31.910]  wait for you to enter a file.
[58:32.530 --> 58:34.570]  Wait for you to enter a digit.
[58:34.590 --> 58:35.390]  Wait for it to say
[58:36.070 --> 58:37.450]  who's entered a digit.
[58:37.450 --> 58:41.190]  And what it says is
[58:41.190 --> 58:42.130]  after you enter a digit,
[58:42.130 --> 58:43.850]  wait for five seconds,
[58:43.850 --> 58:44.990]  and if you look at one, it says
[58:44.990 --> 58:46.870]  it has five words on it.
[58:48.470 --> 58:49.430]  If you enter two,
[58:49.430 --> 58:50.630]  it has seven words on it.
[58:50.630 --> 58:52.130]  If you enter three, it has a thousand words on it.
[58:52.130 --> 58:53.190]  This is really cool.
[58:54.990 --> 58:55.790]  Intermission!
[58:59.650 --> 59:00.570]  Okay, so we have
[59:00.570 --> 59:02.750]  some cool swag to give away.
[59:10.350 --> 59:12.010]  GGM has seen fit to give us
[59:12.010 --> 59:14.230]  props. Apparently, Charles has
[59:14.230 --> 59:16.090]  become very friendly with Mark Spencer,
[59:16.090 --> 59:16.930]  and he sent us
[59:17.910 --> 59:18.790]  very friendly
[59:21.310 --> 59:23.110]  So GGM sent us this whole box
[59:23.110 --> 59:24.890]  of really cool stuff. There's these little
[59:24.890 --> 59:27.070]  CDs with asterisks on them, and they're in the
[59:27.070 --> 59:28.310]  shape of an asterisk.
[59:43.370 --> 59:45.170]  There's asterisk stickers.
[59:51.180 --> 59:52.940]  Yes, if you put
[59:52.940 --> 59:54.860]  the sticker on your car, more people
[59:54.860 --> 59:55.820]  will want it.
[59:58.080 --> 59:58.900]  I also have
[59:58.900 --> 01:00:00.000]  bin racks here, because an old-school
[01:00:00.000 --> 01:00:02.140]  freak.com sticker isn't good.
[01:00:02.280 --> 01:00:03.680]  I have two very
[01:00:03.680 --> 01:00:05.880]  kick-ass sites. You see some of this
[01:00:05.880 --> 01:00:07.680]  in forums almost every day.
[01:00:10.300 --> 01:00:12.120]  Asterisk T-shirts.
[01:00:15.100 --> 01:00:17.680]  So I need four volunteers who want to
[01:00:17.680 --> 01:00:19.700]  come up here and dial phones.
[01:00:22.480 --> 01:00:23.980]  Actually, no. Let's have them answer
[01:00:23.980 --> 01:00:25.100]  questions.
[01:00:25.560 --> 01:00:29.620]  Name a pre-divestiture Bell
[01:00:29.620 --> 01:00:31.440]  operating company.
[01:00:32.100 --> 01:00:35.060]  Pre-divestiture, not 9X.
[01:00:35.140 --> 01:00:36.460]  Pre-divestiture?
[01:00:37.060 --> 01:00:39.160]  Pre-divestiture.
[01:00:40.020 --> 01:00:42.060]  Operating company.
[01:00:45.080 --> 01:00:47.280]  GTE was not a Bell company.
[01:00:49.540 --> 01:00:52.260]  I'm taking over now. Name a post-divestiture
[01:00:52.260 --> 01:00:54.340]  9X regional Bell operating company.
[01:00:54.720 --> 01:00:56.720]  For example, someone already said it.
[01:00:57.760 --> 01:00:59.320]  Raise your hands, people.
[01:00:59.720 --> 01:01:02.360]  Come up.
[01:01:14.270 --> 01:01:16.390]  So, let me wind this thing out of the way.
[01:01:26.570 --> 01:01:28.510]  Each of you sit in front of a telephone.
[01:01:31.610 --> 01:01:34.230]  So, let me prop up this list in front of you here.
[01:01:35.470 --> 01:01:38.170]  This is a touch-tone speed dialing contest,
[01:01:38.170 --> 01:01:39.910]  and for some of you who were in the
[01:01:41.110 --> 01:01:42.950]  game area earlier, we kind of did this
[01:01:42.950 --> 01:01:44.210]  just to work the bugs out.
[01:01:44.270 --> 01:01:47.070]  So, basically, I have a list of numbers here
[01:01:47.070 --> 01:01:48.650]  that I've programmed into my PBX,
[01:01:48.650 --> 01:01:50.830]  and the person who dials these numbers
[01:01:50.830 --> 01:01:52.790]  the fastest and most accurately
[01:01:52.790 --> 01:01:54.790]  will bring my desk phone here
[01:01:54.790 --> 01:01:56.050]  and get a prize.
[01:01:56.110 --> 01:01:57.950]  So, let me set this list up here.
[01:01:59.030 --> 01:02:00.750]  Yeah, I'll explain the rules in just a second.
[01:02:05.590 --> 01:02:07.390]  Unfortunately, these don't do pulse dialing,
[01:02:07.390 --> 01:02:08.750]  otherwise we would do a switch-hook
[01:02:08.750 --> 01:02:10.850]  Can you all read that?
[01:02:15.210 --> 01:02:17.090]  Pardon? Sir, can you read that?
[01:02:17.650 --> 01:02:19.330]  Okay, so what you're going to do is
[01:02:19.330 --> 01:02:21.030]  you're going to pick a phone. Each phone is dialed
[01:02:21.030 --> 01:02:23.170]  one plus the area code plus the number.
[01:02:23.350 --> 01:02:25.030]  After one second, if you dial correctly,
[01:02:25.030 --> 01:02:27.270]  you'll hear another dial tone, dial the next number,
[01:02:27.270 --> 01:02:28.190]  and so on and so on.
[01:02:28.190 --> 01:02:30.710]  If you miss-dial a digit, say you dial
[01:02:30.710 --> 01:02:33.650]  two instead of one, you'll get a reorder tone
[01:02:33.650 --> 01:02:35.190]  after one second, at which point
[01:02:35.190 --> 01:02:37.890]  you will want to dial the number again.
[01:02:38.230 --> 01:02:40.250]  If you skip a digit,
[01:02:40.250 --> 01:02:41.870]  you'll hear nothing after one second.
[01:02:41.870 --> 01:02:44.070]  You may want to press a couple digits
[01:02:44.070 --> 01:02:45.310]  until you get a reorder.
[01:02:45.310 --> 01:02:47.010]  If you get a reorder that
[01:02:47.950 --> 01:02:50.210]  you can't break by dialing,
[01:02:50.210 --> 01:02:54.430]  if you get the reorder where you can't redial the number,
[01:02:56.390 --> 01:02:57.950]  there's rules, there's rules.
[01:02:57.950 --> 01:02:59.790]  If you get the reorder that does not go away
[01:02:59.790 --> 01:03:01.210]  when you start dialing digits,
[01:03:01.210 --> 01:03:03.730]  you screwed up and you have to hang up and start the beginning again.
[01:03:04.270 --> 01:03:05.390]  So,
[01:03:06.150 --> 01:03:07.030]  ready,
[01:03:08.670 --> 01:03:09.550]  set,
[01:03:09.550 --> 01:03:10.270]  go.
[01:03:55.150 --> 01:03:56.150]  Beg pardon?
[01:04:04.450 --> 01:04:05.510]  He wins.
[01:04:06.050 --> 01:04:07.830]  The guy in the Quest shirt.
[01:04:11.260 --> 01:04:13.060]  What size t-shirt do you wear, sir?
[01:04:13.520 --> 01:04:14.780]  What size t-shirt do you wear?
[01:04:15.140 --> 01:04:16.020]  Large? Okay.
[01:04:42.450 --> 01:04:43.470]  He gets to leave.
[01:04:43.470 --> 01:04:44.790]  We need one more contestant.
[01:04:45.330 --> 01:04:46.990]  The guy in the Bell shirt.
[01:04:53.420 --> 01:04:54.800]  You want to switch phones, Natas?
[01:04:55.140 --> 01:04:55.900]  Okay.
[01:04:59.160 --> 01:05:01.860]  We like preferential treatment.
[01:05:05.340 --> 01:05:06.140]  So,
[01:05:06.140 --> 01:05:07.680]  do you understand the rules, sir?
[01:05:08.840 --> 01:05:09.640]  Okay.
[01:05:09.720 --> 01:05:11.220]  On your mark,
[01:05:11.640 --> 01:05:12.880]  go touch the handset.
[01:05:12.880 --> 01:05:14.380]  Don't pick up the handset until I say go.
[01:05:14.380 --> 01:05:15.660]  You can touch the handset.
[01:05:16.560 --> 01:05:18.880]  One plus the area code plus the number, yes.
[01:05:20.480 --> 01:05:21.960]  On your mark, get set,
[01:05:21.960 --> 01:05:22.620]  dial.
[01:05:27.370 --> 01:05:28.350]  Good news, everyone,
[01:05:28.350 --> 01:05:29.470]  I found the numbers.
[01:05:30.230 --> 01:05:30.750]  You can get them in the
[01:05:31.610 --> 01:05:32.630]  capstoneextensions.com.
[01:05:43.180 --> 01:05:43.780]  You know,
[01:05:43.780 --> 01:05:45.540]  Natas, you're really starting to make these sounds
[01:05:45.540 --> 01:05:48.060]  that I know you're...
[01:05:55.180 --> 01:05:56.220]  You flash the hook
[01:05:56.220 --> 01:05:57.100]  and get a call, all right?
[01:05:58.120 --> 01:05:59.980]  He put his own call on hold.
[01:06:00.780 --> 01:06:02.160]  That's what we're...
[01:06:18.840 --> 01:06:19.600]  Yeah, let's do some
[01:06:19.600 --> 01:06:20.220]  bid revenue.
[01:06:20.220 --> 01:06:21.200]  Let's get some free stickers, too.
[01:06:22.880 --> 01:06:24.620]  One of you still got a call on hold.
[01:06:26.500 --> 01:06:28.080]  Call, please.
[01:06:30.080 --> 01:06:31.780]  Natas, would you like an old-school free sticker?
[01:06:32.300 --> 01:06:33.640]  Would you like an old-school free sticker?
[01:06:35.720 --> 01:06:36.780]  He runs the site
[01:06:36.780 --> 01:06:38.100]  for those who don't know.
[01:06:40.080 --> 01:06:41.520]  And what size T-shirt do you wear?
[01:06:43.140 --> 01:06:43.780]  Excellent.
[01:06:55.600 --> 01:06:57.360]  Let's do this. Let me plug the
[01:06:57.360 --> 01:07:00.140]  telephone in so we can hear the winner.
[01:07:03.460 --> 01:07:05.080]  I think we'll do one more,
[01:07:05.080 --> 01:07:06.640]  and then we have to get on with the presentation.
[01:07:08.660 --> 01:07:09.780]  Let's make this fair.
[01:07:10.080 --> 01:07:11.180]  Let's clear this out
[01:07:11.180 --> 01:07:13.140]  and have four all-new people.
[01:07:15.600 --> 01:07:17.360]  If you guys do compete,
[01:07:17.360 --> 01:07:19.600]  come up to me after the show. You'll get swag.
[01:07:19.600 --> 01:07:20.860]  You'll get swag.
[01:07:20.860 --> 01:07:22.600]  You'll get swag. You're welcome.
[01:07:23.000 --> 01:07:25.420]  Okay, new rule. Don't flash so fast
[01:07:25.420 --> 01:07:27.040]  that you put a call on hold.
[01:07:27.040 --> 01:07:27.720]  Yes.
[01:07:32.220 --> 01:07:43.960]  Okay, so,
[01:07:50.170 --> 01:07:53.110]  let's get some volunteers. How about this guy?
[01:07:59.450 --> 01:08:01.530]  You made some funny comments.
[01:08:04.490 --> 01:08:04.590]  Okay.
[01:08:06.670 --> 01:08:11.160]  I heard a patch.
[01:08:15.300 --> 01:08:16.900]  Yes.
[01:08:22.480 --> 01:08:26.400]  Okay, we have one more.
[01:08:30.760 --> 01:08:33.900]  I thought that was my line, Ratchet.
[01:08:36.600 --> 01:08:37.080]  Okay.
[01:08:40.210 --> 01:08:41.730]  Okay, do you guys understand
[01:08:41.730 --> 01:08:43.950]  the rules from last time, or do I need to repeat them?
[01:08:45.950 --> 01:08:47.230]  Okay, yes.
[01:08:47.290 --> 01:08:49.270]  Okay, and now you're able to
[01:08:49.270 --> 01:08:51.810]  listen to your caller.
[01:08:51.810 --> 01:08:53.650]  So, on your mark,
[01:08:53.650 --> 01:08:55.470]  get set,
[01:08:55.470 --> 01:08:56.290]  dial.
[01:08:56.290 --> 01:08:56.630]  Okay.
[01:09:16.920 --> 01:09:18.140]  Don't leave now.
[01:09:18.140 --> 01:09:19.920]  If you want free stuff, don't leave now.
[01:09:19.920 --> 01:09:22.020]  We have various telephonic pieces of equipment
[01:09:22.020 --> 01:09:24.200]  from Star Collection and more asterisks
[01:09:24.200 --> 01:09:25.800]  after the show.
[01:09:40.860 --> 01:09:42.160]  Good afternoon.
[01:09:42.160 --> 01:09:42.920]  Cheers.
[01:09:51.260 --> 01:09:53.230]  Oh, a princess phone.
[01:09:54.420 --> 01:09:55.940]  A princess rotary?
[01:09:59.260 --> 01:10:01.180]  It's little, it's lovely,
[01:10:01.180 --> 01:10:02.420]  but, however, it does not like
[01:10:02.420 --> 01:10:04.340]  what it's a consumer sale model
[01:10:04.340 --> 01:10:05.560]  made out of.
[01:10:06.320 --> 01:10:09.160]  Digium Zap-Tel cards do support rotary phones.
[01:10:09.160 --> 01:10:10.540]  In fact, you can navigate
[01:10:10.540 --> 01:10:13.700]  IPR menus of rotary phones with a Zap-Tel card.
[01:10:15.240 --> 01:10:17.000]  However, the only thing that does
[01:10:17.000 --> 01:10:19.320]  support rotary dial are the card
[01:10:19.320 --> 01:10:20.600]  and the EC.
[01:10:20.820 --> 01:10:23.540]  I think the EC supports rotary dialing.
[01:10:23.540 --> 01:10:24.300]  I'm not sure.
[01:10:24.300 --> 01:10:25.740]  It does? Okay, cool.
[01:10:25.740 --> 01:10:29.180]  So, yeah, this thing does support it.
[01:10:31.300 --> 01:10:32.360]  Unfortunately, no.
[01:10:32.360 --> 01:10:34.180]  This one actually belongs to Mark Spencer
[01:10:34.180 --> 01:10:35.680]  and I had to give it back to him.
[01:10:39.520 --> 01:10:40.840]  Anyway, I found my two
[01:10:41.300 --> 01:10:42.720]  complex, my slightly more complex
[01:10:42.720 --> 01:10:44.280]  and my caller ID.
[01:10:44.280 --> 01:10:46.120]  So, here we go.
[01:10:46.320 --> 01:10:47.660]  Caller ID 1.
[01:10:57.640 --> 01:10:59.360]  This is slightly more complicated.
[01:11:01.260 --> 01:11:03.260]  It sounds like it's going to your AIS script.
[01:11:12.600 --> 01:11:13.680]  I actually replaced
[01:11:13.680 --> 01:11:15.640]  all of the default sounds with JMR
[01:11:15.640 --> 01:11:16.800]  because we used a lot of the
[01:11:17.540 --> 01:11:19.760]  Dell System and Output back in the 1960s
[01:11:19.760 --> 01:11:21.100]  but I really like it more.
[01:11:24.370 --> 01:11:26.090]  You can hear some
[01:11:26.090 --> 01:11:27.290]  slightly more complex script
[01:11:27.290 --> 01:11:29.050]  but I'm going to avoid it for now.
[01:11:47.650 --> 01:11:50.450]  No, baby, give it to me.
[01:11:50.450 --> 01:11:52.570]  Yes, yes, that's it.
[01:11:54.150 --> 01:11:55.530]  And option 3.
[01:11:58.390 --> 01:11:59.870]  This says...
[01:12:01.230 --> 01:12:03.880]  Enter your object now.
[01:12:04.710 --> 01:12:05.510]  Enter your...
[01:12:05.510 --> 01:12:07.670]  This says...
[01:12:10.370 --> 01:12:11.110]  Enter...
[01:12:11.110 --> 01:12:12.130]  This is what's from the
[01:12:12.130 --> 01:12:14.630]  sound file.
[01:12:15.070 --> 01:12:16.470]  I ripped it off from the
[01:12:16.470 --> 01:12:17.830]  information course.
[01:12:17.830 --> 01:12:19.910]  Thank you for making it here.
[01:12:20.470 --> 01:12:32.580]  Send your caller ID to whatever
[01:12:32.580 --> 01:12:34.000]  you want.
[01:12:34.000 --> 01:12:36.400]  After you send your caller ID...
[01:12:51.510 --> 01:12:53.570]  Initial address message.
[01:13:03.550 --> 01:13:26.510]  It was made by
[01:13:26.510 --> 01:13:27.850]  Automatic Electric, which was
[01:13:27.850 --> 01:13:29.870]  GT's manufacturing company.
[01:13:29.950 --> 01:13:32.990]  But it's now discontinued as far as I know.
[01:13:34.470 --> 01:13:36.350]  And ironically, Automatic Electric
[01:13:36.350 --> 01:13:37.390]  is now part of this.
[01:13:37.390 --> 01:13:39.430]  But anyway, you only find the GT5s
[01:13:39.430 --> 01:13:41.830]  typically in former GT territory
[01:13:41.830 --> 01:13:42.890]  and some independent
[01:13:45.350 --> 01:13:46.550]  companies' territories.
[01:13:47.410 --> 01:13:49.250]  However, in the GT5,
[01:13:49.250 --> 01:13:49.910]  Automatic Electric
[01:13:49.910 --> 01:13:50.690]  is an all-around unique
[01:13:50.690 --> 01:13:51.530]  network.
[01:13:51.750 --> 01:13:54.930]  So they decided to test out
[01:13:54.930 --> 01:13:56.090]  each other's networking one day
[01:13:56.090 --> 01:13:57.230]  through this home phone and
[01:13:57.230 --> 01:14:31.530]  decided to list your friends.
[01:14:31.530 --> 01:14:32.390]  I mean, how many times did you
[01:14:32.390 --> 01:14:33.450]  have to call?
[01:14:35.190 --> 01:14:36.230]  You need to create
[01:14:36.230 --> 01:14:38.230]  your neighbor's credit card.
[01:14:39.010 --> 01:14:40.490]  You find your neighbor's credit card
[01:14:40.490 --> 01:14:41.230]  and pay him back.
[01:14:41.230 --> 01:14:44.390]  You don't know where you're calling from, right?
[01:15:05.770 --> 01:15:06.950]  You're obviously
[01:15:07.930 --> 01:15:09.070]  using the same
[01:15:09.070 --> 01:15:11.470]  phone you found your neighbor's card.
[01:15:11.470 --> 01:15:13.170]  I'm not going to take your number.
[01:15:28.020 --> 01:15:29.720]  You just send any caller ID
[01:15:29.720 --> 01:15:31.360]  you can find, any CPM
[01:15:31.360 --> 01:15:32.200]  number.
[01:15:33.320 --> 01:15:35.340]  Oh, you must be selling something to connect
[01:16:24.500 --> 01:16:26.580]  Let's get into the technical details of this later.
[01:16:44.820 --> 01:16:53.600]  You can also, however, do color-ID spoofing most of the time with two lines in your extensions.com file and ask for a CPS.
[01:16:53.600 --> 01:16:55.660]  So, I'm just going to grab some data for you.
[01:16:56.400 --> 01:16:58.420]  We have a lot of theories about color-ID spoofing.
[01:16:58.420 --> 01:17:15.720]  So, I have some.
[01:17:15.720 --> 01:17:29.690]  It's based on the cost of your own number, of some number you want to talk more about.
[01:17:29.690 --> 01:17:35.550]  And then you'll telephone the company, and they'll send you whatever name is associated with that number.
[01:17:40.310 --> 01:17:45.130]  Yeah, it depends on what database you're using, but for the most part, it's fairly easy.
[01:17:45.130 --> 01:17:47.450]  I think I've got a photograph of me doing that.
[01:17:47.450 --> 01:17:51.850]  So, you can see how it works for yourself, your local exchange, your local website.
[01:17:51.850 --> 01:17:54.070]  It's called Remembering a Missing Database.
[01:17:54.070 --> 01:17:56.190]  And then they send that name to you.
[01:18:01.770 --> 01:18:07.030]  It allows you to, if you're doing scanning, you can prioritize the more missing phone numbers.
[01:18:07.370 --> 01:18:09.570]  Here are some real color-ID names.
[01:18:09.570 --> 01:18:13.730]  We've got a company called C.I.A.
[01:18:15.070 --> 01:18:18.270]  It's a really, really cheap reverse lookup.
[01:18:18.270 --> 01:18:20.370]  And you can figure out stuff for yourself.
[01:18:23.570 --> 01:18:25.330]  I'm straight.
[01:18:28.110 --> 01:18:32.070]  I love you strong.
[01:18:32.330 --> 01:18:33.320]  I love you too.
[01:18:34.790 --> 01:18:37.590]  Here's an example of me backspoofing.
[01:18:42.530 --> 01:18:44.270]  You need your credit card, personally.
[01:18:44.270 --> 01:18:45.670]  This time, if it didn't work, you go to Google.
[01:18:49.150 --> 01:18:51.730]  SuperColorID is something that I hacked up in a matter of about five minutes.
[01:18:51.810 --> 01:18:55.290]  It extrapolates tons of useless info from a telephone number.
[01:18:55.570 --> 01:18:57.850]  It gives the name and address from YPH.com.
[01:18:57.850 --> 01:19:01.850]  And it does get you information from the Telecordia location that you've got.
[01:19:01.970 --> 01:19:05.010]  In my office, it works on the telemedicine device, telemedicine terminal.
[01:19:05.010 --> 01:19:08.290]  But if you've got some screen or some window you want to look at, you can do that too.
[01:19:09.190 --> 01:19:13.210]  This is a version of it that has a site, oldschooltrees.com, that doesn't use the word.
[01:19:13.210 --> 01:19:14.950]  That just grabs the address from the web.
[01:19:15.090 --> 01:19:17.150]  Here's a photo of me using SuperColorID,
[01:19:17.150 --> 01:19:21.190]  and looking from Gladstone's Corned Fish restaurant at Pacific Palisades,
[01:19:21.190 --> 01:19:22.950]  to my own phone number.
[01:19:23.530 --> 01:19:24.410]  Yes.
[01:19:29.430 --> 01:19:31.930]  Wow, people are making their own versions for their own country.
[01:19:31.930 --> 01:19:35.170]  Someone's got an Amazon copy from Australia, that works in Australia.
[01:19:35.170 --> 01:19:37.390]  So, sweet stuff.
[01:19:37.390 --> 01:19:38.710]  So you can see here,
[01:19:38.710 --> 01:19:40.610]  it does the number,
[01:19:42.310 --> 01:19:43.450]  the address,
[01:19:43.450 --> 01:19:44.930]  so this spins up your webpages,
[01:19:44.930 --> 01:19:47.510]  this is the calling party name, that tells you who's the phone company,
[01:19:47.510 --> 01:19:49.490]  and here is all the details,
[01:19:49.490 --> 01:19:50.670]  how the solution is served out,
[01:19:50.670 --> 01:19:52.730]  how many information, prefixes,
[01:19:52.730 --> 01:19:54.790]  where the switch is, what time the switch is,
[01:19:55.250 --> 01:19:56.810]  and, for example,
[01:19:56.810 --> 01:19:58.890]  if it's useless for anybody but their own country,
[01:19:58.890 --> 01:20:00.550]  you can just enter, like,
[01:20:00.550 --> 01:20:02.630]  Apple, or Google, or anything like this.
[01:20:04.970 --> 01:20:05.850]  What?
[01:20:07.730 --> 01:20:08.170]  Um...
[01:20:08.170 --> 01:20:09.650]  No, it does not.
[01:20:15.170 --> 01:20:17.730]  You can rig radio podcasts.
[01:20:18.770 --> 01:20:20.630]  Yeah, why don't you explain this?
[01:20:22.330 --> 01:20:23.410]  What radio does is,
[01:20:23.410 --> 01:20:24.390]  they have a hunt group,
[01:20:24.390 --> 01:20:25.730]  that's what it was,
[01:20:25.730 --> 01:20:28.110]  you call one number, and it hunts for a free line.
[01:20:29.290 --> 01:20:32.190]  So, for example, you call 5-8000,
[01:20:32.190 --> 01:20:33.190]  and the reality is,
[01:20:33.190 --> 01:20:33.330]  it hunts for a free line,
[01:20:33.330 --> 01:20:33.670]  which is, you know,
[01:20:33.670 --> 01:20:34.810]  8-000-1, 8-000-2,
[01:20:34.810 --> 01:20:35.470]  8-000-3,
[01:20:35.470 --> 01:20:35.830]  8-000-3,
[01:20:35.830 --> 01:20:36.870]  8-000-3,
[01:20:37.770 --> 01:20:38.690]  8-000-3,
[01:20:38.690 --> 01:20:40.390]  8-000-3,
[01:20:40.390 --> 01:20:40.810]  8-000-3,
[01:20:40.810 --> 01:20:45.510]  8-000-3,
[01:20:45.510 --> 01:20:47.170]  8-000-3,
[01:20:47.170 --> 01:20:48.730]  8-000-3,
[01:20:51.590 --> 01:20:54.450]  8-000-3,
[01:20:54.450 --> 01:20:58.490]  8-000-3,
[01:20:58.490 --> 01:20:59.770]  and what happens is,
[01:20:59.770 --> 01:21:00.950]  after the hunt is over,
[01:21:00.950 --> 01:21:17.200]  I think our provider for
[01:21:17.200 --> 01:21:19.080]  Defcon by phone claimed that we can have
[01:21:19.700 --> 01:21:21.200]  probably over 600 calls
[01:21:21.200 --> 01:21:22.980]  going on at the same time.
[01:21:24.960 --> 01:21:27.080]  We do have a DS1,
[01:21:27.080 --> 01:21:28.240]  otherwise known as a T1,
[01:21:28.240 --> 01:21:31.630]  and a DS3,
[01:21:31.630 --> 01:21:31.730]  and a DS4,
[01:21:32.310 --> 01:21:33.590]  and a DS5,
[01:21:33.590 --> 01:21:34.650]  and a DS6,
[01:21:53.880 --> 01:21:55.260]  and what it basically does,
[01:21:55.260 --> 01:21:58.460]  you tell Asterisk,
[01:21:58.460 --> 01:22:02.780]  generate a bunch of
[01:22:02.780 --> 01:22:04.580]  different radio stations,
[01:22:04.580 --> 01:22:06.860]  to connect to a certain radio station.
[01:22:06.860 --> 01:22:08.340]  So, what happens,
[01:22:08.340 --> 01:22:09.000]  call file one,
[01:22:09.000 --> 01:22:09.880]  sorry I'm call number two,
[01:22:09.880 --> 01:22:11.340]  call file three,
[01:22:12.300 --> 01:22:13.780]  sorry I'm call ID number three,
[01:22:13.780 --> 01:22:15.120]  now I've got it set up to work,
[01:22:15.120 --> 01:22:17.220]  and it leads out bound calls,
[01:22:17.220 --> 01:22:18.960]  and you can do more,
[01:22:19.560 --> 01:22:20.940]  generate call file number four,
[01:22:20.940 --> 01:22:22.100]  and actually stuff gets done,
[01:22:22.100 --> 01:22:24.280]  call number five, call number six, call number seven,
[01:22:24.280 --> 01:22:25.960]  and you're looking at call number nine,
[01:22:25.960 --> 01:22:27.280]  and all of a sudden,
[01:22:27.280 --> 01:22:38.190]  the calls that are currently in the queue
[01:22:38.190 --> 01:22:39.930]  after the call is over,
[01:22:39.930 --> 01:22:43.130]  you say, hey, oh my god, I won,
[01:22:43.130 --> 01:22:44.590]  and I say yes,
[01:22:44.590 --> 01:22:45.390]  and all of a sudden,
[01:22:45.390 --> 01:22:51.700]  I'm sure radio station guy number one
[01:22:51.700 --> 01:22:54.600]  is going to be highly confused,
[01:22:54.600 --> 01:22:55.540]  and he says, well, they don't know
[01:22:55.540 --> 01:22:56.800]  what's going to fix this,
[01:22:56.800 --> 01:22:59.000]  that's why I actually found something out this week,
[01:22:59.000 --> 01:23:00.300]  and they solved the problem,
[01:23:00.300 --> 01:23:01.840]  and I'm not going to tell you what's going to happen.
[01:23:08.300 --> 01:23:09.760]  Yeah, American Idol,
[01:23:09.760 --> 01:23:11.400]  or some, if you watch TV,
[01:23:11.400 --> 01:23:12.680]  I don't watch TV anymore,
[01:23:14.040 --> 01:23:21.070]  and I said, well,
[01:23:21.070 --> 01:23:22.570]  gee, this is important for the voting
[01:23:22.570 --> 01:23:24.270]  mind, for the worst guy that was ever
[01:23:24.270 --> 01:23:25.610]  listed on the list,
[01:23:26.130 --> 01:23:26.970]  and I said, well,
[01:23:26.970 --> 01:23:32.620]  if you do that, and they get a record contract,
[01:23:32.620 --> 01:23:35.780]  radio will get about 1.1% worse.
[01:24:38.020 --> 01:24:38.660]  What's your
[01:24:38.660 --> 01:24:40.840]  NMAT5 voting number? Let's just do this.
[01:24:41.960 --> 01:24:42.940]  On your
[01:24:42.940 --> 01:24:44.120]  exchange, right?
[01:24:56.030 --> 01:24:57.570]  Enter the IP address
[01:24:57.570 --> 01:24:59.170]  you wish to scan.
[01:25:08.600 --> 01:25:09.600]  Oh, that's it.
[01:25:09.600 --> 01:25:11.820]  You know how to push my button.
[01:25:12.000 --> 01:25:13.260]  Please wait.
[01:25:14.900 --> 01:25:16.060]  Host found with
[01:25:16.060 --> 01:25:18.020]  17 ports open.
[01:25:18.220 --> 01:25:19.860]  Echo on port 7.

[01:25:39.660 --> 01:25:40.580]  And that's it.
[01:27:09.870 --> 01:27:10.510]  On Friday,
[01:27:10.510 --> 01:27:11.470]  just fixing bugs and
[01:27:11.470 --> 01:27:12.630]  dealing with things.
[01:28:21.900 --> 01:28:22.740]  You don't have to.
[01:28:27.930 --> 01:28:28.770]  All of him,
[01:28:28.770 --> 01:28:29.870]  he thought of all the phrases
[01:28:29.870 --> 01:28:31.210]  except the recording.
[01:28:32.310 --> 01:28:34.190]  After recording everything,
[01:28:34.190 --> 01:28:35.510]  I got really crazy and recorded
[01:28:35.610 --> 01:28:37.490]  a whole bunch of crazy introductory phrases.
[01:28:38.130 --> 01:28:40.010]  Okay, so,
[01:28:40.010 --> 01:28:42.390]  you're basically ignoring how weird it is
[01:28:42.390 --> 01:28:43.470]  to see phone calls
[01:28:43.470 --> 01:28:45.370]  and recordings of yourself.
[01:28:46.110 --> 01:28:47.990]  It still freaks me out.
[01:28:48.810 --> 01:28:49.810]  So, there's a search
[01:28:49.810 --> 01:28:51.050]  to be able to ignore calls,
[01:28:51.050 --> 01:28:52.970]  there's a reminder, and again,
[01:28:52.970 --> 01:28:54.290]  you need to register.
[01:28:56.790 --> 01:28:58.510]  How does it work?
[01:28:58.510 --> 01:28:59.670]  There's a MySQL database,
[01:28:59.670 --> 01:29:03.650]  and there's a whole bunch of audio clips.
[01:29:03.650 --> 01:29:04.710]  And pretty much,
[01:29:04.710 --> 01:29:07.190]  I spent a week in front of my computer
[01:29:07.190 --> 01:29:09.150]  dictating the entire text
[01:29:09.150 --> 01:29:10.550]  of the schedule.
[01:29:24.370 --> 01:29:26.090]  There's registration,
[01:29:26.090 --> 01:29:27.710]  reminders,
[01:29:33.700 --> 01:29:35.380]  and there's a web interface
[01:29:35.380 --> 01:29:36.520]  internally.
[01:29:53.750 --> 01:29:55.750]  To hear a listing of shows
[01:29:55.750 --> 01:29:57.470]  that are coming up in the next hour,
[01:29:57.470 --> 01:29:58.310]  press 1.
[01:30:05.250 --> 01:30:07.770]  Please enter the first 5 letters
[01:30:07.770 --> 01:30:09.770]  of the title of the show you'd like to see,
[01:30:09.770 --> 01:30:11.490]  followed by the talent sign.
[01:30:13.110 --> 01:30:15.070]  Presentation ID 56.
[01:30:15.070 --> 01:30:16.850]  Be your own telephone company.
[01:30:16.850 --> 01:30:17.830]  With Asterix.
[01:30:17.830 --> 01:30:20.590]  Presented by Strom Carlson and Black Ratchett.
[01:30:20.590 --> 01:30:22.490]  In Parthenon 3 and 4.
[01:30:22.490 --> 01:30:23.310]  Starting at
[01:30:23.310 --> 01:30:26.630]  Saturday, July 30, 2005
[01:30:28.590 --> 01:30:31.290]  at 7 o'clock p.m.
[01:30:31.290 --> 01:30:31.930]  Running for
[01:30:31.930 --> 01:30:33.750]  110 minutes.
[01:30:33.750 --> 01:30:35.010]  To hear more about this event,
[01:30:35.010 --> 01:30:35.770]  press 1.
[01:30:35.770 --> 01:30:37.190]  To skip to the next event,
[01:30:37.190 --> 01:30:38.170]  press 2.
[01:30:38.310 --> 01:30:39.590]  If you hear more about the event,
[01:30:39.590 --> 01:30:41.750]  it brings you back to the entire description of the talk
[01:30:41.750 --> 01:30:43.170]  as printed in the schedule.
[01:30:47.720 --> 01:30:49.340]  Shouts to Strom!
[01:30:50.940 --> 01:30:52.880]  If any of you want to hire me
[01:30:52.880 --> 01:30:54.480]  for your voiceovers, please come see me.
[01:30:54.480 --> 01:30:55.780]  I'll give you my contact information.
[01:30:55.780 --> 01:30:58.540]  But don't give me 48 pages of show descriptions, please.
[01:30:58.540 --> 01:30:59.540]  Prefer sanity.
[01:30:59.820 --> 01:31:01.060]  No, I think I can handle that.
[01:31:02.500 --> 01:31:04.740]  It's cheaper than buying that damn stuff for us.
[01:31:05.880 --> 01:31:06.900]  The problem?
[01:31:06.960 --> 01:31:08.740]  Dictating the whole schedule is a pain in the ass.
[01:31:08.740 --> 01:31:10.200]  I didn't realize how long it would take
[01:31:10.200 --> 01:31:11.620]  to dictate the whole thing in.
[01:31:11.620 --> 01:31:13.720]  We were rushing.
[01:31:14.040 --> 01:31:16.920]  It was supposed to be less than a week ago.
[01:31:16.920 --> 01:31:18.640]  I'm not used to it.
[01:31:18.640 --> 01:31:19.960]  I'm not used to it.
[01:31:19.980 --> 01:31:22.520]  We had some jitter issues last week.
[01:31:23.560 --> 01:31:25.260]  There were so many problems.
[01:31:25.260 --> 01:31:27.720]  We couldn't nail all calls at the same time.
[01:31:28.060 --> 01:31:29.340]  And we had jitter problems.
[01:31:29.340 --> 01:31:30.600]  We had to switch to SIP.
[01:31:30.760 --> 01:31:32.820]  And it's really difficult to keep our schedule in sync
[01:31:32.820 --> 01:31:33.640]  with DEF CON's schedule.
[01:31:33.640 --> 01:31:36.040]  We went and asked them to please
[01:31:36.040 --> 01:31:38.940]  give us all your scheduled updates
[01:31:38.940 --> 01:31:40.360]  to inform our users
[01:31:40.790 --> 01:31:43.680]  and everyone who calls in about changes.
[01:31:43.720 --> 01:31:44.640]  I don't remember
[01:31:44.640 --> 01:31:45.760]  getting my email address
[01:31:45.760 --> 01:31:48.160]  out of the entire agenda.
[01:31:48.300 --> 01:31:50.080]  So thank you, everyone.
[01:31:50.280 --> 01:31:51.820]  And also this.
[01:31:51.820 --> 01:31:52.580]  We came up to them and said,
[01:31:52.580 --> 01:31:54.140]  hey, our schedule really sucks.
[01:31:54.140 --> 01:31:57.180]  Is there someplace we can go to get updates?
[01:31:57.240 --> 01:31:59.440]  Oh, go to updates.defcon.org.
[01:31:59.440 --> 01:32:02.640]  So I was like, okay, I'll sit down, fix everything.
[01:32:02.640 --> 01:32:04.940]  Not a single schedule change on there.
[01:32:05.060 --> 01:32:06.680]  I was...
[01:32:07.320 --> 01:32:08.660]  It's causing nightmares.
[01:32:08.660 --> 01:32:09.800]  I don't have nightmares for you.
[01:32:09.820 --> 01:32:12.640]  We spent all of Monday, or all of Friday
[01:32:12.640 --> 01:32:14.280]  trying to deal with the fact that they pushed
[01:32:14.280 --> 01:32:16.440]  the entire track date back an hour.
[01:32:17.380 --> 01:32:19.720]  But we hadn't anticipated that.
[01:32:20.060 --> 01:32:21.100]  I'm sorry?
[01:32:23.660 --> 01:32:25.200]  What we should do next year
[01:32:25.200 --> 01:32:26.640]  is we're probably going to set up something
[01:32:26.640 --> 01:32:28.700]  where the schedule is actually
[01:32:28.700 --> 01:32:30.560]  thrown together in our system.
[01:32:31.520 --> 01:32:33.020]  And that's the idea I had.
[01:32:33.020 --> 01:32:34.260]  The schedule is thrown together in our system
[01:32:34.260 --> 01:32:35.680]  so we automatically know about it
[01:32:35.680 --> 01:32:37.560]  and have everything synchronized.
[01:32:37.560 --> 01:32:39.580]  And as a disclaimer, we all love DEF CON.
[01:32:39.580 --> 01:32:40.980]  We're not trying to piss anyone off,
[01:32:40.980 --> 01:32:42.840]  but this is what happens.
[01:32:42.840 --> 01:32:44.140]  When we're at DEF CON reminders,
[01:32:44.140 --> 01:32:45.520]  there's no way to detect whether users
[01:32:45.520 --> 01:32:48.920]  are rejected by scale.
[01:32:48.980 --> 01:32:51.320]  So they don't get thrown into the reminder.
[01:32:51.660 --> 01:32:53.040]  Some users are brain-deficient
[01:32:53.040 --> 01:32:54.360]  and forget their thing.
[01:32:55.220 --> 01:32:57.540]  And you've got to call from somebody.
[01:32:58.780 --> 01:33:01.040]  You know who you are.
[01:33:07.590 --> 01:33:08.710]  Rejector.net.
[01:33:08.710 --> 01:33:10.910]  We'll be back next year.
[01:33:10.910 --> 01:33:12.750]  We'll be back next year.
[01:33:13.270 --> 01:33:15.650]  The problem with Crack 2 is that
[01:33:15.650 --> 01:33:17.330]  they said, we'll move everything up and down,
[01:33:17.330 --> 01:33:19.690]  OK, that's fine. I update the schedule.
[01:33:19.690 --> 01:33:21.290]  And they said, OK, let's make that time
[01:33:21.290 --> 01:33:23.930]  so everything is on schedule by the end.
[01:33:23.930 --> 01:33:25.890]  I cried when I finally found out.
[01:33:26.310 --> 01:33:28.070]  There was no way to do that.
[01:33:28.070 --> 01:33:29.170]  I want to get to the Q&A
[01:33:29.170 --> 01:33:30.270]  because I'm sure there are a lot of you
[01:33:30.270 --> 01:33:31.050]  who wrote the Q&A.
[01:33:31.350 --> 01:33:33.930]  The CDF cards kind of flake out.
[01:33:34.390 --> 01:33:37.630]  They're problems because asterisk is TTL
[01:33:37.630 --> 01:33:39.330]  but all folks know how to do the asterisk
[01:33:56.030 --> 01:34:01.130]  So, if you want to ask a question, there is a telephone there.
[01:34:01.170 --> 01:34:02.990]  Queue up in front of the telephone.
[01:34:03.910 --> 01:34:06.630]  And for those of you watching on TV,
[01:34:06.630 --> 01:34:14.150]  call the following number, area code 213-415-1047,
[01:34:14.150 --> 01:34:16.210]  and you will be in the Q&A queue.
[01:34:16.210 --> 01:34:20.430]  Do not call this number if you are sitting here in the room.
[01:34:20.690 --> 01:34:24.570]  If you see someone who is on their phone and calling the number
[01:34:24.570 --> 01:34:28.570]  and holding and asking a question, grab their phone and throw it to me,
[01:34:28.570 --> 01:34:30.490]  and we won't give it back to them.
[01:34:35.810 --> 01:34:39.630]  Will you please pick up and dial 8-1-1-0?
[01:34:39.730 --> 01:34:42.570]  Oh, shoot. Sorry about that.
[01:34:44.190 --> 01:34:45.750]  Please pick up that phone.
[01:34:55.790 --> 01:34:56.790]  Hello?
[01:34:57.550 --> 01:34:59.090]  I have a question.
[01:34:59.670 --> 01:35:00.670]  Really?
[01:35:06.050 --> 01:35:08.910]  Okay, please, everyone calm down. We are trying to get to make questions.
[01:35:08.910 --> 01:35:12.970]  The codec that was demonstrated earlier, you can do rock and roll, funk,
[01:35:12.970 --> 01:35:16.130]  with a lot of bass, and a yelling guy,
[01:35:16.130 --> 01:35:18.610]  and a very quiet dude with his band going.
[01:35:19.030 --> 01:35:23.170]  The band was really good to get that music, like,
[01:35:23.170 --> 01:35:28.940]  I don't know if codecs are nice for speech, but the way I see it,
[01:35:28.940 --> 01:35:32.760]  if you portrait test a codec, you see what they really sound like
[01:35:32.760 --> 01:35:34.280]  under all circumstances.
[01:35:34.420 --> 01:35:37.460]  Because not all speech is perfect.
[01:35:37.460 --> 01:35:38.900]  So if you portrait test a codec,
[01:35:38.900 --> 01:35:43.240]  you get a clearer picture of what it really sounds like.
[01:35:47.080 --> 01:35:49.620]  Yeah, it's a good test. I know it's not designed for music,
[01:35:49.620 --> 01:35:51.140]  but there is music on hold.
[01:35:51.340 --> 01:35:53.340]  What happens when you're driving in your car,
[01:35:53.340 --> 01:35:55.860]  and you have tons of background noise, and you're trying to use one of these?
[01:35:55.920 --> 01:35:56.880]  Same thing.
[01:35:56.880 --> 01:35:57.520]  Okay.
[01:36:00.080 --> 01:36:01.040]  Thank you very much.
[01:36:01.040 --> 01:36:01.780]  Thank you.
[01:36:03.940 --> 01:36:06.520]  Let's see if anyone's calling in from the TV.
[01:36:10.160 --> 01:36:13.260]  Agent logged in.
[01:36:13.860 --> 01:36:15.300]  Hello?
[01:36:18.320 --> 01:36:19.760]  Hello?
[01:36:20.140 --> 01:36:21.680]  Black call!
[01:36:21.680 --> 01:36:24.200]  Let's hang up and get the next person in line.
[01:36:25.860 --> 01:36:28.240]  Agent logged in.
[01:36:36.330 --> 01:36:37.730]  Calling in? Wow!
[01:36:37.730 --> 01:36:39.510]  More people at home!
[01:36:40.810 --> 01:36:44.870]  If you're watching on TV call, okay, let's get you in.
[01:36:53.140 --> 01:36:55.040]  Okay, two questions, actually.
[01:36:55.040 --> 01:36:58.480]  One, for all the color-ID speech and stuff you guys were talking about,
[01:36:58.480 --> 01:37:01.360]  do you need a DS1, an MP3, or a PN?
[01:37:01.360 --> 01:37:04.000]  No, I've got it running on my DSL connection.
[01:37:04.160 --> 01:37:07.520]  Okay, so just with the VoIP provider...
[01:37:07.520 --> 01:37:09.920]  Yeah, your standard VoIP call, even with MULA,
[01:37:09.920 --> 01:37:13.280]  only requires 80 kilobits per second of bandwidth plus overhead.
[01:37:13.280 --> 01:37:18.240]  So if you've got more than 80 kilobits per second connection in both directions, you're fine.
[01:37:18.240 --> 01:37:19.040]  Okay.
[01:37:21.360 --> 01:37:22.220]  Okay, never mind.
[01:37:22.220 --> 01:37:26.140]  The other question I had is, what is the difference between a phone company and a telephone company?
[01:37:28.950 --> 01:37:30.690]  How many phones do you want to use?
[01:37:30.690 --> 01:37:34.610]  You can get generally about the same as a phone company, between three and five telephone sets.
[01:37:40.260 --> 01:37:41.920]  Run, Forrest, run!
[01:37:42.580 --> 01:37:44.780]  Isn't this scavenger hunt over yet?
[01:37:44.800 --> 01:37:45.460]  No.
[01:37:45.740 --> 01:37:47.920]  There's a giant bee problem with DEF CONNORS here.
[01:37:47.920 --> 01:37:48.640]  Thank you.
[01:37:58.760 --> 01:38:01.480]  Hello, you're with Asterisk.
[01:38:02.500 --> 01:38:03.280]  Hey, how you doing?
[01:38:03.280 --> 01:38:04.360]  Hey, how you doing?
[01:38:04.640 --> 01:38:05.420]  Hey!
[01:38:05.420 --> 01:38:06.800]  There's a little delay.
[01:38:09.560 --> 01:38:11.060]  What's your question, sir?
[01:38:11.760 --> 01:38:13.660]  My question on DEF CONNORS.
[01:38:13.660 --> 01:38:15.580]  Are those the only ones that are supported?
[01:38:16.240 --> 01:38:18.840]  For interfacing your phones with Asterisk?
[01:38:19.180 --> 01:38:20.140]  Yeah.
[01:38:20.140 --> 01:38:20.660]  No.
[01:38:20.660 --> 01:38:22.880]  No, they're not the only ones supported.
[01:38:22.920 --> 01:38:23.920]  I believe you're...
[01:38:23.920 --> 01:38:24.820]  Yeah.
[01:38:25.260 --> 01:38:26.940]  No, they're not the only ones supported.
[01:38:26.940 --> 01:38:28.040]  I don't know which one it is.
[01:38:28.040 --> 01:38:31.480]  I think it's something called VoiceTel that uses the same hardware.
[01:38:31.480 --> 01:38:33.280]  It was the same older version of it.
[01:38:33.280 --> 01:38:34.160]  It's supported.
[01:38:34.160 --> 01:38:34.900]  It works.
[01:38:35.080 --> 01:38:35.480]  But...
[01:38:35.480 --> 01:38:37.000]  Good luck getting it working.
[01:38:39.760 --> 01:38:41.540]  So, are those PCI cards?
[01:38:41.540 --> 01:38:42.740]  Yes, they're PCI.
[01:38:42.740 --> 01:38:45.940]  And I believe there's also one with ISA for you to use with...
[01:38:47.540 --> 01:38:48.960]  I believe you're running...
[01:38:49.560 --> 01:38:50.180]  Okay.
[01:38:50.180 --> 01:38:51.020]  ...DEF CONNORS.
[01:38:51.020 --> 01:38:51.760]  DEF CONNORS, right?
[01:38:51.760 --> 01:38:52.440]  Yes.
[01:38:53.340 --> 01:38:55.100]  This is actually on the DEF CON by VoiceTel.
[01:38:55.100 --> 01:38:56.620]  But we're going to move on to the next question.
[01:38:56.620 --> 01:38:59.380]  Okay, let's get the next question from a real person.
[01:39:06.850 --> 01:39:07.550]  Marty?
[01:39:07.590 --> 01:39:09.250]  Hey, could you...
[01:39:17.150 --> 01:39:21.050]  For the most part, Asterisk is about as secure as a regular telephone,
[01:39:21.050 --> 01:39:23.870]  although the new version of the ETH protocol now does encryption.
[01:39:23.870 --> 01:39:24.810]  I haven't played with it yet.
[01:39:24.810 --> 01:39:26.110]  It's only about two weeks old.
[01:39:26.110 --> 01:39:29.790]  But there is now encryption built into the TVS head version of the ETH protocol.
[01:39:30.510 --> 01:39:32.050]  Cool. Okay.
[01:39:32.110 --> 01:39:33.790]  Let's take a call from...
[01:39:44.750 --> 01:39:45.790]  Hello?
[01:39:58.570 --> 01:40:00.110]  Oh, this was always right here.
[01:40:13.780 --> 01:40:41.930]  The reason those payphones take an incredibly long time to call...
[01:40:41.930 --> 01:40:48.810]  Also, it works from my mobile phone.
[01:40:48.970 --> 01:40:50.150]  So it's not our...
[01:40:50.150 --> 01:40:53.150]  The other fun thing about the payphones out in the lobby
[01:40:53.150 --> 01:40:56.130]  is that they do not transmit a payphone code.
[01:40:56.130 --> 01:40:58.950]  So therefore, you can actually use DEF CON by phone from them.
[01:40:58.950 --> 01:41:01.970]  All payphones are banned because we don't feel like being charged a fee.
[01:41:01.970 --> 01:41:04.650]  However, thanks to Goldetel, whoever supports them,
[01:41:04.650 --> 01:41:08.810]  they have a very unincorrect standard on their payphones
[01:41:08.810 --> 01:41:11.730]  and they treat them as being real payphones.
[01:41:15.290 --> 01:41:16.470]  Hello, caller?
[01:41:20.110 --> 01:41:21.230]  Grab his phone!
[01:41:49.070 --> 01:41:50.430]  ...and O'Reilly makes great books.
[01:41:50.430 --> 01:41:52.970]  This one's apparently like 570 something pages.
[01:41:53.350 --> 01:41:55.630]  I'm looking for a good book with a starfish on the cover.
[01:41:56.030 --> 01:41:56.990]  And secondly...
[01:41:58.290 --> 01:42:00.350]  Sure, I'm broke. I'll accept the money.
[01:42:00.810 --> 01:42:02.410]  You won't pay me. I've got it down for you.
[01:42:02.690 --> 01:42:03.990]  Alright, thank you.
[01:42:26.150 --> 01:42:27.730]  Call in somebody from...
[01:42:27.730 --> 01:42:29.050]  Hello, party?
[01:42:30.930 --> 01:42:31.650]  Hello?
[01:42:32.150 --> 01:42:34.520]  Hello.
[01:42:34.880 --> 01:42:37.340]  Up to four people can be in the queue at any given time.
[01:42:38.760 --> 01:42:44.300]  And how did you figure out that you're the inventor?
[01:42:44.820 --> 01:42:47.700]  Because we're dialing our internal Dundee net number.
[01:42:47.700 --> 01:42:49.600]  We got skills, yo.
[01:42:49.760 --> 01:42:54.260]  Yeah. Actually, you can set a password for this, but for convenience,
[01:42:54.260 --> 01:42:57.480]  since none of you from the outside world can dial on our Dundee plan,
[01:42:58.280 --> 01:43:00.500]  we figured it would just be easier if we could just answer the question
[01:43:00.500 --> 01:43:02.240]  instead of getting some password thing.
[01:43:02.240 --> 01:43:06.460]  Yes, essentially, this allows you to set up your own phone sets.
[01:43:06.780 --> 01:43:09.040]  Yes. Thank you much.
[01:43:23.920 --> 01:43:25.040]  I'm wearing...
[01:43:35.230 --> 01:43:38.250]  I've got this really, really nice butt set.
[01:43:39.990 --> 01:43:44.210]  Have you played with any of the 802.11c voice phones?
[01:43:44.910 --> 01:43:48.370]  I haven't played with any of the 802.11c voice phones.
[01:43:48.370 --> 01:43:53.010]  There are phones that'll act like cordless phones, except they'll talk to your Wi-Fi network.
[01:43:53.390 --> 01:43:56.330]  I wasn't kidding when I told you I had a really nice butt set.
[01:43:58.250 --> 01:44:00.570]  7920? Okay, so 7920.
[01:44:00.610 --> 01:44:05.430]  If you go to voice-info.org wiki, they have information on all of those.
[01:44:05.550 --> 01:44:08.470]  I haven't played with the Wi-Fi phone set.
[01:44:10.630 --> 01:44:12.890]  Yeah, yeah, you can do voice talk on BDSU.
[01:44:12.890 --> 01:44:14.630]  Yes, I set them up for my own thing.
[01:44:14.630 --> 01:44:18.450]  I have a nice Bluetooth headset. I have Wi-Fi hotspot. It comes right in hand.
[01:44:18.450 --> 01:44:21.330]  We've got to go wrap this up. Thank you all for coming.
[01:44:21.730 --> 01:44:24.310]  I'm going to send out shouts to binrev.com.
[01:44:24.310 --> 01:44:27.230]  You can find Strom and I there on forums, binrev.com.
[01:44:28.190 --> 01:44:30.530]  Anything else? Oldschoolfreak.com.
[01:44:30.530 --> 01:44:34.010]  We have stickers that we can give people. Just follow us out.
[01:44:34.010 --> 01:44:36.610]  We'll talk to your questions and do whatever.
[01:44:37.650 --> 01:44:40.790]  Hang on just a second. You can also, before you go,
[01:44:40.790 --> 01:44:43.190]  if you have any questions and you can't get to us directly,
[01:44:43.190 --> 01:44:47.190]  my telephone number is on my website, so call me up there.
[01:44:47.410 --> 01:44:51.310]  Further reading of resources, on to the slideshow on your TV.
[01:44:51.310 --> 01:44:53.090]  Thank you for coming, everybody.
