WEBVTT 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 --> 00:23.240 I'm Strom Carlson, and this is Black Ratchet, 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 --> 00:43.380 See, if Alex thought that we're actually here, we'd give him the payphone, but I guess he's not, so you lose, Alex. 00:43.380 --> 00:43.900 Sorry. 00:47.280 --> 00:48.800 So, let's get started. 00:48.820 --> 00:53.860 Actually, before we get started, I just want to test the phone 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 --> 02:03.440 So, first off, what is Asterisk? 02:03.440 --> 02:04.640 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 --> 02:11.880 Sweet. 02:12.720 --> 02:14.100 You're in for fun. 02:14.120 --> 02:15.040 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 --> 02:30.700 PBX is a private brand exchange. 02:30.700 --> 02:32.040 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 --> 02:43.020 It's now version 1.0.8. 02:43.020 --> 02:43.920 It's a stable 1.0. 02:45.380 --> 02:47.620 1.0.9 is a stable 1.0? 02:47.780 --> 02:48.200 Yeah. 02:48.200 --> 02:48.840 Okay. 02:53.700 --> 02:56.700 We just ran the latest bleeding edge version. 02:56.720 --> 02:57.840 So, why Asterisk? 02:57.840 --> 02:59.540 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 --> 03:17.020 So if you can do this yourself, and this is very easy to do yourself, it will save you a lot of money if you're running a company. 03:17.020 --> 03:23.060 And if you're a hobbyist, it's really cool because you can set up your own phone network 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 --> 03:33.460 In fact, this little tiny laptop that Ratchet is typing on right now 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 --> 04:53.920 Here's a sample Asterisk installation. 04:53.920 --> 04:56.640 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 --> 05:02.220 Thanks, thanks. 05:02.320 --> 05:03.940 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 --> 05:20.080 There are Sun machines here. 05:20.080 --> 05:24.560 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 --> 05:36.060 They all work. 05:36.060 --> 05:40.180 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 --> 05:56.800 There are IP telephones you can buy second-hand on the market. 05:56.800 --> 05:58.140 They're not all that expensive. 05:58.260 --> 06:00.120 This is the Cisco 7960. 06:00.120 --> 06:01.300 This is an IP phone. 06:01.840 --> 06:04.220 You can get those for about $250 online. 06:04.220 --> 06:05.500 In fact, I looked on eBay. 06:05.620 --> 06:08.300 I think I saw them going used for $150. 06:09.520 --> 06:12.320 If you look for deals, I've gotten one for $120. 06:12.320 --> 06:14.860 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 --> 06:36.400 There are crappy telephones you can get. 06:36.400 --> 06:39.840 You can get the Grandstream Budget Home 100, used about $40. 06:39.840 --> 06:46.980 It's roughly equivalent to that $9.95 phone you buy at the drugstore 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 --> 07:14.540 Most VoIP phones are built the same. 07:14.540 --> 07:16.700 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 --> 07:40.020 And that's called the EECS-E. 07:40.020 --> 07:41.240 And I think I have one here. 08:01.880 --> 08:03.700 This is the EECS-E. 08:03.700 --> 08:04.900 A little tidy thing. 08:04.940 --> 08:09.980 You plug in an analog telephone in one end and you plug your Ethernet connection in the other end. 08:09.980 --> 08:12.440 And your analog phone is now a VoIP phone. 08:12.440 --> 08:13.460 This is $100. 08:14.760 --> 08:18.520 You can also get the Sephora SPA-2002. 08:18.520 --> 08:20.600 We've got those here running. 08:20.600 --> 08:22.040 And these are about $70. 08:22.040 --> 08:25.780 You can plug two Vana Ratchet. 08:29.540 --> 08:31.860 These speak SIF instead of EECS. 08:31.860 --> 08:36.100 You can plug two analog telephones into these and get two dial tones and that's about $70. 08:36.100 --> 08:41.540 You can get the Grandstream HandyTone 286 for about $65. 08:42.360 --> 08:44.500 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 --> 08:53.860 You can also... there's tons more of these. 08:53.860 --> 09:02.240 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 --> 09:14.140 You can also buy something called a Zaptel card. 09:14.240 --> 09:21.460 And these are cards you put in your asterisk box and you connect analog telephones and telephone lines to these cards. 09:21.560 --> 09:24.520 The one on the top is the TDM-400P. 09:24.520 --> 09:26.420 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 --> 10:30.460 Those are really hard to find, in my opinion. 10:30.460 --> 10:35.380 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 --> 11:09.820 The main protocol for interconnecting voice over IP calls is called SIP. 11:09.820 --> 11:11.860 It stands for Session Initiation Protocol. 11:11.860 --> 11:15.160 It's a signaling protocol only. 11:15.560 --> 11:17.600 It only signals and sets up calls. 11:17.600 --> 11:21.920 All it does is contact your box and say, hey, I have a good call for you. 11:21.920 --> 11:23.100 You might want to connect to it. 11:23.100 --> 11:24.460 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 --> 11:37.980 It was developed by the ITF, not ITU. 11:37.980 --> 11:40.180 It uses URLs instead of telephone numbers. 11:40.180 --> 11:44.480 For example, you won't connect to 3-1-1-5-5-5-2-3-6-8. 11:44.480 --> 11:50.300 You'll enter it into SIP, stromcharleston.com, which doesn't work on Thread. 11:50.560 --> 11:52.900 It's intended to be a peer-to-peer protocol. 11:53.060 --> 11:54.940 It's not like a general server. 11:54.940 --> 11:57.160 It goes to my box next to Strom's. 11:57.300 --> 12:02.060 It doesn't have to contact anybody for it to work. 12:02.060 --> 12:04.040 There are certain caveats to that. 12:04.040 --> 12:05.340 We'll get into those later. 12:05.340 --> 12:08.660 The main advantage of SIP is that it's very ubiquitous. 12:08.660 --> 12:10.060 It's supported by everybody. 12:10.060 --> 12:15.220 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 --> 12:27.660 It does not play well with NAT. 12:27.660 --> 12:29.520 It's very hard to actually set up with NAT. 12:29.520 --> 12:32.760 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 --> 12:46.180 I'm at 192.168.0.252, and Strom's loss of VoIP. 12:47.020 --> 12:49.700 So there's a lot of workarounds for it. 12:49.700 --> 12:53.240 What you have to do is you have to tell it to, you know, this is my external IP address. 12:53.240 --> 12:54.660 Use this for everything. 12:54.980 --> 12:57.480 Don't care about whatever your IP address is. 12:57.580 --> 13:00.060 However, in my opinion, it's a bit of a kludge. 13:00.880 --> 13:05.180 The other protocol, before there was SIP, there was H.323. 13:05.180 --> 13:07.700 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 --> 13:18.540 Like, for example, SS7 or something. 13:18.540 --> 13:20.540 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 --> 13:42.600 Although, by the way, although this is a telephone talk, please turn your ringers off. 13:42.600 --> 13:43.540 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 --> 14:27.780 What Mark wanted to do is he wanted to, you know, took a look at SIP, took a look at H3.23, and said, Boy, these are crap. 14:27.820 --> 14:29.240 Let's go design a mining protocol. 14:29.640 --> 14:32.780 It does not suffer from NAT traversal issues. 14:32.960 --> 14:40.660 For example, I'm behind a firewall I call Strom, and, you know, it knows that where I'm coming from, you know, 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 --> 14:55.240 That's the only thing you have to open up in your firewall as opposed to RTP, 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 --> 15:36.800 It's a protocol for many PSTN termination providers because, you know, a lot of PSTN termination providers, 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 --> 18:54.260 So more resolution is given to the lower amplitudes, where most of the voice frequency is, 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 --> 19:28.800 Adaptive differential pulse code modulation, well first, differential pulse code modulation, 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 --> 19:52.420 Adaptive differential PCM uses a varying number of bits, depending on the complexity of that sample, 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 --> 20:09.820 It's linear predictive coding, and it basically, it's pretty complex, but the basic thing is that it uses vocoders to compress speech. 20:09.920 --> 20:18.140 And it tends to work pretty well for speech, but there's a lot of electronic music nowadays 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 --> 20:46.420 North American uses mu law companding, most of the rest of the world uses a-law companding, which is almost identical, but slightly different, but for all intents and purposes, they sound exactly the same. 20:47.000 --> 20:56.080 If you're in 64 kilobits, if you're doing something called bit-probing, 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 --> 21:37.160 That box that does 790 simultaneous calls, if you have it do GSM or one of the lower bandwidth codecs, 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 --> 23:33.490 Here's the benefits. 23:33.490 --> 23:34.970 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 --> 24:16.470 Just in order for me to be able to call Ratchet's box and have one telephone conversation over the codec, we each had to pay $10. 24:17.950 --> 24:24.030 That's only for one call, so if you want to have more than one call using this codec, $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 --> 24:55.350 I mean, I've heard people rave about Skype. 24:55.350 --> 24:55.810 I hear it. 24:55.810 --> 24:57.390 I hear it just like ILBC. 24:58.630 --> 25:01.530 There's also Speaks, which is an open source codec. 25:01.530 --> 25:04.050 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 --> 28:31.850 If they ever get a recording contract, buy their album. 28:31.850 --> 28:33.610 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 --> 29:07.570 So let's talk about getting Asterisk to talk to the real phone network, because this is all fun and cool, 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 --> 29:18.210 It's called Nuphone. 29:18.510 --> 29:21.370 Nuphone, uh, well, you know more about Nuphone than I do. 29:21.370 --> 29:22.190 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 --> 29:37.350 They're very geared toward Asterisk. 29:37.350 --> 29:45.070 I believe they support this only under a nice public high-pride, saying, you know, I want to be assisted by, you know, a supporter or some other ADA. 29:45.450 --> 29:56.450 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, which has some interesting, you know, applications to it. 29:56.450 --> 29:57.710 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 --> 30:34.750 They're very easygoing. 30:34.830 --> 30:44.750 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, 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 --> 31:41.090 Now, for the longest time, what would happen is, you know, like, your call would not go through or you'd get an intercept saying, like, 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 --> 31:49.690 And for someone like me, who's phone-free and enjoys calling intercepts, it was a bit of a bummer. 31:49.990 --> 31:56.030 But, you know, a couple weeks ago, oh, a couple months ago, by now, they actually turned it on. 31:56.030 --> 32:07.110 I called with a payphone out in Boston and I got, you know, I'm sorry, the phone number you've reached is not accepted. 32:07.110 --> 32:12.090 I literally picked up the phone and called him and said, 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 --> 32:32.850 CONSTED, directed for dial numbers, which are basically numbers you would call on, you would set up on the PSTN, so mom, dad, you know, your sister, someone who doesn't have an asterisk can call you and actually reach you on your woodline. 32:32.850 --> 32:39.290 The only numbers they have are in Michigan, which for me, I guess, is okay 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 --> 32:51.590 For example, during Strong and Lucky 55's presentation last year on freaking in the age of voice over IP, 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 --> 33:02.210 It's not there yet. 33:02.210 --> 33:02.950 Stand up. 33:03.770 --> 33:04.430 Here's Mr. 33:04.430 --> 33:05.110 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 --> 34:04.380 And, of course, AMI-II. 34:04.380 --> 34:06.640 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 --> 34:36.960 It's actually gotten better. 34:36.960 --> 34:40.560 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 --> 36:02.900 And the other thing is that inbound numbers with Voice Calls Connect, 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 --> 37:12.360 If you call a number that's been disconnected, and the phone company that you're giving it to says, 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 --> 37:56.500 They also send you this little pin, which is this logo, 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 --> 38:06.960 Yes, at least one person here at DEF CON is walking around with a Broadvoice pin, 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 --> 38:12.660 He's not here? 38:12.660 --> 38:13.260 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 --> 38:33.400 Most of these other carriers will just deliver the number, but these people will actually do a name level and deliver the name for you. 38:33.400 --> 38:40.860 So we'll see not just that 311-555-2368 is calling you, 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 --> 38:50.960 So if you want to do EECS termination or if you're trying to firewall or something, you've got to do some sort of EECS proxy 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 --> 39:37.040 Okay, 39:40.520 --> 39:41.400 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 --> 40:30.610 What you do is you register your number in 2-1-2-3-4-5-5-2-3-6-8, and you register it to a URL. 40:30.610 --> 40:32.370 And then someone queries their enum server 40:35.750 --> 40:37.410 , then, over the Internet. 40:42.720 --> 40:53.590 But then you realize that local exchanges can't access 2-1-1-5 numbers, 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 --> 41:20.500 you can offer free termination of $800, 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 --> 41:39.300 Okay, if we all pay attention to the top, basically, I'm at the top of my phone, 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 --> 41:53.040 So I pick up my handset, dial it, 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 --> 42:00.500 So what I set up my DVX to do is talk to a medium circle. 42:00.960 --> 42:05.100 And it says, hey, do you know 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 --> 42:10.660 And essentially, in this example, it says, yes, it's a bell at telephone.com. 42:10.660 --> 42:19.020 So it registers that to my DVX, at which point my DVX goes, ooh, I guess I'll go over to the internet.com rather than picking up a local line. 42:19.020 --> 42:24.980 And it goes over the internet, and I dial 3-1-1-5-5-5-2-3-6-8 down here, which they also 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 --> 42:34.900 It's a very top-down way of looking at things. 42:34.900 --> 42:37.920 It's centrally managed, centrally served, and centrally centralized. 42:37.920 --> 42:47.420 Basically, they wanted developers exactly like DNS and have, you know, 15 root servers all over the world, which is great, but no one actually has done it yet. 42:49.960 --> 42:54.440 And it's not being used 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 --> 43:03.940 My idea is how logically they save you money, you know. 43:03.940 --> 43:10.940 I can charge you 5 cents a minute for, you know, and it's nowhere near where it would last. 43:11.300 --> 43:17.820 We're working towards a really nice solution that's starting to get there, but at the same point, you know... 43:28.880 --> 43:30.240 Something like that, yeah. 43:30.240 --> 43:32.160 So last April, what someone set out with 43:45.290 --> 43:48.110 is a fully peer-to-peer E164 solution. 43:48.110 --> 43:48.330 It's a fully peer-to-peer E164 solution . 43:48.330 --> 43:53.050 Basically , you know, it sets up 43:57.400 --> 43:59.520 your own telephone network for fresh for 44:04.530 --> 44:05.410 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 --> 44:45.180 So, we've got this DBS here, and it talks to this node over here, and what this node does, it only has one node, and what it does is it reaches that node, and that node talks to only this one, and it reaches the DBS node, it's got a dial, 3, 5, 5, 2, 5, 44:45.180 --> 44:58.710 6, at which point, it scrolls back and says, hey, 411 service, this is all it. 45:03.480 --> 45:12.800 Basically, it's a very good peer-to-peer setup, which has some problems with Dundee, in my opinion, also. 45:13.040 --> 45:33.120 To be honest, I mean, essentially, what I could start doing is I could start advertising, hey, all the numbers to the White House, send them to me, so I can, you know, start World War III, scalability, we're not sure how it's going to be still relatively small, 45:33.120 --> 45:36.600 but I've never seen a product like Nutella. 45:36.600 --> 45:38.340 Look how many problems we had with that. 45:38.820 --> 45:46.960 It's not officially a standard yet, we just submitted it to IETF, but as we all know, standards cost money, and these people don't have it. 45:48.080 --> 45:53.640 Right now, it's only officially in DBS, and we can submit it, 45:59.810 --> 46:10.850 and run it against 109, or 107, or whatever, and get some support in it, and in my opinion, it works fine, and also in my opinion, I think the eye of the beholder should be nice. 46:14.600 --> 46:19.920 Quality assurance, what quality 46:23.200 --> 46:39.660 assurance do you charge for your for your phone call going out over your WAN, for example, I don't have quality assurance for my WAN, or for example, 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 --> 46:54.370 Sorry, I forgot to dial something in my PBX earlier. 46:55.730 --> 46:58.050 Basically, there are two ways you can use QoS here. 46:58.050 --> 47:12.090 There's priority QoS, which can give you a way back to priority over any other factor, where you can basically reserve your WAN and turn it away and get the rest of it for it. 47:12.090 --> 47:15.730 But for everything that's not QoS, you get the rest of the WAN. 47:16.750 --> 47:21.210 I'm sure there's more about that, but I'm a phone person, not a router person. 47:21.570 --> 47:25.970 Many residential routers are now voice aware and will do the sort of thing right out of the box. 47:26.490 --> 47:42.040 And you can also if you're a control freak, or if you want to do it on a larger scale, then you can connect your router and say , hey, I've got a super router phone and I've sort of gotten working and I'm definitely not a super router person. 47:42.920 --> 47:47.620 So now let's get into the cool part of what you can do with Asterisk. 47:47.660 --> 47:54.260 And by the way, if you're watching on TV in the hotel, 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 --> 48:10.260 So 48:15.660 --> 48:16.540 , Asterisk Gateway Interface. 48:16.540 --> 48:20.680 What it is, is an interface for adding 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 --> 48:32.180 You infer, you see, you PHP, Lisp, PCL, anything that uses standard in and standard out, you can use it. 48:32.600 --> 48:37.980 And basically, since Asterisk is the best thing since sliced bread, I find AGI to be the best thing since sliced bread. 48:38.500 --> 48:41.960 Because you can basically do anything you want with it 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 --> 48:52.180 What it is, is basically, I don't know if you can actually see it 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 --> 49:02.720 This is what apparently electricity parts don't work. 49:04.240 --> 49:08.760 So, basically, a lot of my presentation of this part hasn't been done. 49:11.260 --> 49:17.900 Starting from here, basically, what it is, is start on a standard in point, standard in and standard out. 49:17.900 --> 49:25.100 Basically, what Asterisk does is it reads all the variables in and checks all of it. 49:25.100 --> 49:36.780 It checks to make sure, 200 times per day, 5 times per day, that we're not sure about the quality and it means that you just keep on going. 49:38.400 --> 49:47.600 Basically, what happens is after you read all the variables in and make sure they're OK, what it does is, it streams a file that says, your caller ID is... 49:47.600 --> 49:51.220 and it says, you recheck your caller ID. 49:51.560 --> 49:53.400 So, here's how it works. 49:53.680 --> 49:55.320 I've backed up here, but 50:02.070 --> 50:07.270 the one we're really interested in is AGI caller ID, which says 311-555-2368. 50:07.470 --> 50:12.830 And then it says, after it's done feeding all the variables, it says 200 results here, it means I'm done in 41 minutes. 50:12.830 --> 50:16.470 It says, OK, stream file, you know, AGI caller ID. 50:19.790 --> 50:22.250 Then it says, OK, I'm done, what do you want me to do? 50:22.410 --> 50:32.530 OK, stream pages, 311-555-2368, AGI command that asterisk understands, and it goes, you know, says 3, 1, 1, 50:35.720 --> 50:37.720 200 results here, OK, I'm done. 50:37.760 --> 50:40.400 And at which point it says, hang up, I'm done. 50:41.500 --> 50:46.240 It takes it back to me, sends back, you know, 200 results here, I'm done now, it hangs up. 50:50.060 --> 50:53.180 Yes, exactly, AGI caller ID readback, ENAC. 50:56.620 --> 50:59.940 Now, that's a lot of work to do in what's 51:03.030 --> 51:07.950 called asterisk AGI, which is a Perl module for asterisk in writing AGI scripts. 51:08.270 --> 51:10.590 It simplifies a lot of AGI programming. 51:10.590 --> 51:15.450 Essentially, it takes out a lot of the dirty work and takes away everyone's doing the work that you don't have to. 51:15.450 --> 51:19.950 It allows the AGI to control the simple object interface in Perl. 51:20.210 --> 51:32.430 The problem is, I subscribed to the mailing list a few months ago, and it's been dead silent for the last few months ago, and someone said, is this mailing list still active? 51:32.550 --> 51:34.650 At which point I'm going to be not able to work anymore. 51:34.870 --> 51:41.870 Maybe I should set up another thing, or maybe a few people should sign up to it and start using it yourselves. 51:42.410 --> 51:50.150 What it is, is it allows the AGI to easily integrate with Perl, which easily integrates with almost anything in the known universe. 51:50.230 --> 51:59.910 And it's available at asterisk.uniter.net which is a very strange German word 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 --> 52:07.490 I think we can test this out at least 100% to about 10 lines or so. 52:07.590 --> 52:15.070 So this is, you know, it reads in, you know, starts up a new object called AGI. 52:15.270 --> 52:21.050 You know that entire, you know, 10 line thing, check the variables, make sure they're okay. 52:21.070 --> 52:22.210 It does it all automatically. 52:23.710 --> 52:30.690 And the other feature that the other one didn't have is you did not check whether or not the person had a caller ID in the first place. 52:31.250 --> 52:36.410 So you basically, if you didn't have a caller ID, you did a file file saying, the caller ID is, and then it would hang up. 52:36.410 --> 52:45.790 Or what this one does is it checks to see if your caller ID is, you know, what this would do if you didn't have a caller ID, 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 --> 52:49.070 It 52:52.260 --> 52:55.380 checks to see if your caller ID is on touch-tone. 52:55.900 --> 52:59.700 Basically, everyone knows how to use it, including your mom. 53:00.360 --> 53:02.900 However, you know, it's very limited on what you can do with it. 53:02.900 --> 53:09.200 For example, you have to use the sign-up function to use it, or, you know, you can only use it if you have five members. 53:09.200 --> 53:09.940 The 53:15.530 --> 53:17.970 XML, it's extensible. 53:18.570 --> 53:19.690 WebPXML is extensible. 53:19.690 --> 53:25.650 VoiceXML is basically an XML that allows for scripting with a voice interface. 53:25.650 --> 53:26.450 It's extensible. 53:26.450 --> 53:28.690 The problem with Asterisk is that it has no relatively 53:33.420 --> 53:42.240 new open-source program called Asterisk PDF, which says it has Asterisk CIFS. 53:43.040 --> 53:46.220 So I spent about two weeks trying to get this compiled. 53:46.220 --> 53:48.800 It's a high-resolution demonstration. 53:48.800 --> 53:51.340 There's also commercial offerings. 53:51.340 --> 53:54.920 For example, Microsoft has a new VXML program where 53:58.210 --> 54:05.150 there's, like, at least two or three commercial ones that I know of that are also free open-source. 54:05.650 --> 54:08.230 VXML is still, you know, you need to use 54:12.960 --> 54:13.460 . 54:31.420 --> 54:35.640 Think back to that Texas speech program you played with in, like, 1987. 54:37.020 --> 54:41.900 That program is called Cepstral. 54:41.900 --> 54:42.200 Cepstral is 54:47.520 --> 54:52.620 a free free -for-download free-for-download program 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 --> 55:35.440 You can play with a free version of Cepstral, but it's also a sound file and every fifth or tenth word or something goes please register me. 55:36.380 --> 55:47.860 Yeah, and it is free for download , like you said, and you can make sure if you ever have, like, you know, one of the programs and you want to make sure that it works with your program you can set it up and, you know, you just have to do that please register me every time it works or something. 55:49.360 --> 55:51.460 The other thing for output is reports. 55:51.740 --> 55:53.440 You can get your stuff for free. 55:54.040 --> 55:58.400 The other person is Allison and she has huge support for Asterisk. 55:58.820 --> 56:02.740 It's for pay and she has lots of fan sayings available on the internet. 56:02.960 --> 56:08.240 Asterisk also comes with a whole ton of sayings and she says all sorts of crazy stuff in the LA area. 56:17.760 --> 56:28.920 A friend of mine actually just wanted to test her and so he sent her increasingly offensive scripts and I think he finally found her a little bit after... 56:28.920 --> 56:31.060 yeah, a long time. 56:33.100 --> 56:36.180 Well, maybe she'll read Richard Nixon's Social Security number, I don't know. 56:37.440 --> 56:37.960 Basically 56:44.600 --> 56:45.740 , we have a... 56:57.110 --> 56:59.810 I'm not a weather fan, my name is Ron. 57:01.870 --> 57:02.790 Phone! 57:03.630 --> 57:05.990 I'll show you my phone voice in a second. 57:37.730 --> 57:40.410 And now a demonstration by Scott Carlson 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 --> 57:48.550 Script getting tested, Blamer approved. 57:49.650 --> 57:52.410 To hear what's coming up in the next hour, press 1. 57:52.410 --> 57:54.510 To search for an event, press 2. 57:54.510 --> 57:57.970 To need feedback from DEF CON My Phone team, press 0. 57:59.010 --> 58:00.230 And so on. 58:04.530 --> 58:11.770 If any of you want to write down silly things on slips of paper and leave them up here, I'll do them for you. 58:11.770 --> 58:12.090 Here's 58:16.410 --> 58:19.690 a slightly more complex thing, this actually uses input and output. 58:20.150 --> 58:23.330 Basically, what it does is I've got three ways of doing it. 58:23.330 --> 58:31.910 One of those is using CGI, and basically it lets you forever wait for you to enter a file. 58:32.530 --> 58:34.570 Wait for you to enter a digit. 58:34.590 --> 58:37.450 Wait for it to say who's entered a digit. 58:37.450 --> 58:46.870 And what it says is after you enter a digit, wait for five seconds, and if you look at one, it says it has five words on it. 58:48.470 --> 58:50.630 If you enter two, 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 --> 59:02.750 Okay, so we have some cool swag to give away. 59:10.350 --> 59:12.930 GGM has seen fit to give us props. 59:13.330 --> 59:24.030 Apparently, Charles has become very friendly with Mark Spencer, and he sent us very friendly So GGM sent us this whole box of really cool stuff. 59:24.030 --> 59:28.310 There's these little CDs with asterisks on them, and they're in the shape of an asterisk. 59:43.370 --> 59:45.170 There's asterisk stickers. 59:51.180 --> 59:55.820 Yes, if you put the sticker on your car, more people will want it. 59:58.080 --> 01:00:02.140 I also have bin racks here, because an old-school freak.com sticker isn't good. 01:00:02.280 --> 01:00:04.780 I have two very kick-ass sites. 01:00:04.780 --> 01:00:07.680 You see some of this in forums almost every day. 01:00:10.300 --> 01:00:12.120 Asterisk T-shirts. 01:00:15.100 --> 01:00:19.700 So I need four volunteers who want to come up here and dial phones. 01:00:22.480 --> 01:00:23.220 Actually, no. 01:00:23.220 --> 01:00:25.100 Let's have them answer questions. 01:00:25.560 --> 01:00:31.440 Name a pre-divestiture Bell 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 --> 01:00:51.080 I'm taking over now. 01:00:51.080 --> 01:00:54.340 Name a post-divestiture 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 --> 01:01:44.210 This is a touch-tone speed dialing contest, and for some of you who were in the game area earlier, we kind of did this just to work the bugs out. 01:01:44.270 --> 01:01:56.050 So, basically, I have a list of numbers here that I've programmed into my PBX, and the person who dials these numbers the fastest and most accurately will bring my desk phone here 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 --> 01:02:10.850 Unfortunately, these don't do pulse dialing, otherwise we would do a switch-hook Can you all read that? 01:02:15.210 --> 01:02:16.050 Pardon? 01:02:16.050 --> 01:02:17.090 Sir, can you read that? 01:02:17.650 --> 01:02:20.150 Okay, so what you're going to do is you're going to pick a phone. 01:02:20.150 --> 01:02:23.170 Each phone is dialed one plus the area code plus the number. 01:02:23.350 --> 01:02:28.190 After one second, if you dial correctly, you'll hear another dial tone, dial the next number, and so on and so on. 01:02:28.190 --> 01:02:37.890 If you miss-dial a digit, say you dial two instead of one, you'll get a reorder tone after one second, at which point you will want to dial the number again. 01:02:38.230 --> 01:02:41.870 If you skip a digit, you'll hear nothing after one second. 01:02:41.870 --> 01:02:45.310 You may want to press a couple digits until you get a reorder. 01:02:45.310 --> 01:02:57.950 If you get a reorder that you can't break by dialing, if you get the reorder where you can't redial the number, there's rules, there's rules. 01:02:57.950 --> 01:03:03.730 If you get the reorder that does not go away when you start dialing digits, you screwed up and you have to hang up and start the beginning again. 01:03:04.270 --> 01:03:10.270 So, ready, set, 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 --> 01:04:15.640 Large? 01:04:15.640 --> 01:04:16.020 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 --> 01:05:07.680 So, do you understand the rules, sir? 01:05:08.840 --> 01:05:09.640 Okay. 01:05:09.720 --> 01:05:12.880 On your mark, 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 --> 01:05:22.620 On your mark, get set, dial. 01:05:27.370 --> 01:05:29.470 Good news, everyone, I found the numbers. 01:05:30.230 --> 01:05:32.630 You can get them in the capstoneextensions.com. 01:05:43.180 --> 01:05:48.060 You know, Natas, you're really starting to make these sounds that I know you're... 01:05:55.180 --> 01:05:57.100 You flash the hook 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 --> 01:06:20.220 Yeah, let's do some 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 --> 01:06:38.100 He runs the site 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 --> 01:06:56.280 Let's do this. 01:06:56.280 --> 01:07:00.140 Let me plug the telephone in so we can hear the winner. 01:07:03.460 --> 01:07:06.640 I think we'll do one more, 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 --> 01:07:13.140 Let's clear this out and have four all-new people. 01:07:15.600 --> 01:07:18.540 If you guys do compete, come up to me after the show. 01:07:18.540 --> 01:07:19.600 You'll get swag. 01:07:19.600 --> 01:07:20.860 You'll get swag. 01:07:20.860 --> 01:07:21.760 You'll get swag. 01:07:21.760 --> 01:07:22.600 You're welcome. 01:07:23.000 --> 01:07:24.040 Okay, new rule. 01:07:24.040 --> 01:07:27.040 Don't flash so fast that you put a call on hold. 01:07:27.040 --> 01:07:27.720 Yes. 01:07:32.220 --> 01:07:33.340 Okay, 01:07:37.200 --> 01:07:43.960 so, 01:07:50.170 --> 01:07:51.750 let's get some volunteers. 01:07:51.750 --> 01:07:53.110 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 --> 01:08:43.950 Okay, do you guys understand 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 --> 01:08:51.810 Okay, and now you're able to listen to your caller. 01:08:51.810 --> 01:08:56.290 So, on your mark, get set, 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 --> 01:09:25.800 We have various telephonic pieces of equipment from Star Collection and more asterisks 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 --> 01:10:05.560 It's little, it's lovely, but, however, it does not like what it's a consumer sale model made out of. 01:10:06.320 --> 01:10:09.160 Digium Zap-Tel cards do support rotary phones. 01:10:09.160 --> 01:10:13.700 In fact, you can navigate IPR menus of rotary phones with a Zap-Tel card. 01:10:15.240 --> 01:10:20.600 However, the only thing that does support rotary dial are the card 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 --> 01:10:24.980 It does? 01:10:24.980 --> 01:10:25.740 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 --> 01:10:35.680 This one actually belongs to Mark Spencer and I had to give it back to him. 01:10:39.520 --> 01:10:44.280 Anyway, I found my two complex, my slightly more complex 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 --> 01:11:21.100 I actually replaced all of the default sounds with JMR because we used a lot of the Dell System and Output back in the 1960s but I really like it more. 01:11:24.370 --> 01:11:29.050 You can hear some slightly more complex script 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 --> 01:12:14.630 This is what's from the sound file. 01:12:15.070 --> 01:12:17.830 I ripped it off from the information course. 01:12:17.830 --> 01:12:19.910 Thank you for making it here. 01:12:20.470 --> 01:12:21.210 Send 01:12:31.220 --> 01:12:34.000 your caller ID to whatever 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 --> 01:13:04.190 It 01:13:25.530 --> 01:13:29.870 was made by Automatic Electric, which was 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 --> 01:13:37.390 And ironically, Automatic Electric is now part of this. 01:13:37.390 --> 01:13:46.550 But anyway, you only find the GT5s typically in former GT territory and some independent companies' territories. 01:13:47.410 --> 01:13:51.530 However, in the GT5, Automatic Electric is an all-around unique network. 01:13:51.750 --> 01:13:57.590 So they decided to test out each other's networking one day through this home phone and decided to 01:14:30.830 --> 01:14:31.530 list your friends. 01:14:31.530 --> 01:14:33.450 I mean, how many times did you have to call? 01:14:35.190 --> 01:14:38.230 You need to create your neighbor's credit card. 01:14:39.010 --> 01:14:41.230 You find your neighbor's credit card 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 --> 01:15:11.470 You're obviously using the same 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 --> 01:15:32.200 You just send any caller ID you can find, any CPM 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 --> 01:16:59.000 So, I have 01:17:15.240 --> 01:17:15.720 some. 01:17:15.720 --> 01:17:17.380 It's based on the cost 01:17:26.910 --> 01:17:29.690 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 --> 01:19:22.950 Here's a photo of me using SuperColorID, and looking from Gladstone's Corned Fish restaurant at Pacific Palisades, 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 --> 01:19:53.670 So you can see here, it does the number, the address, so this spins up your webpages, this is the calling party name, that tells you who's the phone company, and here is all the details, how the solution is served out, how many information, prefixes, where the switch is, 01:19:53.670 --> 01:20:02.630 what time the switch is, and, for example, if it's useless for anybody but their own country, you can just enter, like, 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 --> 01:20:28.110 What radio does is, they have a hunt group, that's what it was, you call one number, and it hunts for a free line. 01:20:29.290 --> 01:21:00.950 So, for example, you call 5-8000, and the reality is, it hunts for a free line, which is, you know, 8-000-1, 8-000-2, 8-000-3, 8-000-3, 8-000-3, 8-000-3, 8 -000-3, 8 -000-3, 8-000-3, 8-000-3, 8-000-3, 8-000-3, 8-000-3, and what happens is, after the hunt is over, 01:21:00.950 --> 01:21:10.070 I think our 01:21:16.620 --> 01:21:22.980 provider for Defcon by phone claimed that we can have probably over 600 calls going on at the same time. 01:21:24.960 --> 01:21:34.650 We do have a DS1, otherwise known as a T1, and a DS3, and a DS4, and a DS5, and a DS6, 01:21:53.880 --> 01:22:06.860 and what it basically does, you tell Asterisk, generate a bunch of different radio stations, to connect to a certain radio station. 01:22:06.860 --> 01:22:22.100 So , what happens, call file one, sorry I'm call number two, call file three, sorry I'm call ID number three, now I've got it set up to work, and it leads out bound calls, and you can do more, generate call file number four, and actually stuff gets done, 01:22:22.100 --> 01:22:28.040 call number five, call number six, call number seven, and you're looking at call number nine, and all of a sudden, the 01:22:36.890 --> 01:22:56.800 calls that are currently in the queue after the call is over, you say, hey, oh my god, I won, and I say yes, and all of a sudden, I'm sure radio station guy number one is going to be highly confused, and he says , well, they don't know what's going to fix this, 01:22:56.800 --> 01:23:01.840 that's why I actually found something out this week, and they solved the problem, and I'm not going to tell you what's going to happen. 01:23:08.300 --> 01:23:14.760 Yeah, American Idol, or some, if you watch TV, I don't watch TV anymore, and I 01:23:19.010 --> 01:23:35.780 said, well, gee, this is important for the voting mind, for the worst guy that was ever listed on the list, and I said, well, if you do that, and they get a record contract, radio will get about 1.1% worse. 01:24:38.020 --> 01:24:39.620 What's your NMAT5 voting number? 01:24:39.620 --> 01:24:40.840 Let's just do this. 01:24:41.960 --> 01:24:44.120 On your exchange, right? 01:24:56.030 --> 01:24:59.170 Enter the IP address 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 --> 01:25:18.020 Host found with 17 ports open. 01:25:18.220 --> 01:25:19.860 Echo on port 7. 01:25:20.040 --> 01:25:21.920

that's it. 01:27:09.870 --> 01:27:12.630 On Friday, just fixing bugs and dealing with things. 01:28:21.900 --> 01:28:22.740 You don't have to. 01:28:27.930 --> 01:28:31.210 All of him, he thought of all the phrases except the recording. 01:28:32.310 --> 01:28:37.490 After recording everything, I got really crazy and recorded a whole bunch of crazy introductory phrases. 01:28:38.130 --> 01:28:45.370 Okay, so, you're basically ignoring how weird it is to see phone calls and recordings of yourself. 01:28:46.110 --> 01:28:47.990 It still freaks me out. 01:28:48.810 --> 01:28:54.290 So, there's a search to be able to ignore calls, there's a reminder, and again, you need to register. 01:28:56.790 --> 01:28:58.510 How does it work? 01:28:58.510 --> 01:29:03.650 There's a MySQL database, and there's a whole bunch of audio clips. 01:29:03.650 --> 01:29:10.550 And pretty much, I spent a week in front of my computer dictating the entire text of the schedule. 01:29:24.370 --> 01:29:27.710 There's registration, reminders, 01:29:33.700 --> 01:29:36.520 and there's a web interface internally. 01:29:53.750 --> 01:29:58.310 To hear a listing of shows that are coming up in the next hour, press 1. 01:30:05.250 --> 01:30:11.490 Please enter the first 5 letters of the title of the show you'd like to see, 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 --> 01:30:31.290 Starting at Saturday, July 30, 2005 at 7 o'clock p.m. 01:30:31.290 --> 01:30:33.750 Running for 110 minutes. 01:30:33.750 --> 01:30:35.770 To hear more about this event, press 1. 01:30:35.770 --> 01:30:38.170 To skip to the next event, press 2. 01:30:38.310 --> 01:30:43.170 If you hear more about the event, it brings you back to the entire description of the talk as printed in the schedule. 01:30:47.720 --> 01:30:49.340 Shouts to Strom! 01:30:50.940 --> 01:30:54.480 If any of you want to hire me 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 --> 01:31:11.620 I didn't realize how long it would take 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 --> 01:31:33.640 And it's really difficult to keep our schedule in sync with DEF CON's schedule. 01:31:33.640 --> 01:31:43.680 We went and asked them to please give us all your scheduled updates to inform our users and everyone who calls in about changes. 01:31:43.720 --> 01:31:48.160 I don't remember getting my email address 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 --> 01:31:54.140 We came up to them and said, 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 --> 01:32:16.440 We spent all of Monday, or all of Friday trying to deal with the fact that they pushed 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 --> 01:32:30.560 What we should do next year is we're probably going to set up something where the schedule is actually thrown together in our system. 01:32:31.520 --> 01:32:33.020 And that's the idea I had. 01:32:33.020 --> 01:32:37.560 The schedule is thrown together in our system so we automatically know about it 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 --> 01:32:42.840 We're not trying to piss anyone off, but this is what happens. 01:32:42.840 --> 01:32:48.920 When we're at DEF CON reminders, there's no way to detect whether users 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 --> 01:32:54.360 Some users are brain-deficient 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 --> 01:33:18.570 The problem with Crack 2 is that they said, we'll move everything up and down, OK, that's fine. 01:33:18.570 --> 01:33:19.690 I update the schedule. 01:33:19.690 --> 01:33:23.930 And they said, OK, let's make that time 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 --> 01:33:31.050 I want to get to the Q&A because I'm sure there are a lot of you who wrote the Q&A. 01:33:31.350 --> 01:33:33.930 The CDF cards kind of flake out. 01:33:34.390 --> 01:33:39.330 They're problems because asterisk is TTL 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 --> 01:34:16.210 And for those of you watching on TV, call the following number, area code 213-415-1047, 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 --> 01:34:30.490 If you see someone who is on their phone and calling the number and holding and asking a question, grab their phone and throw it to me, 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 --> 01:34:41.290 Oh, shoot. 01:34:41.290 --> 01:34:42.570 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 --> 01:35:07.610 Okay, please, everyone calm down. 01:35:07.610 --> 01:35:08.910 We are trying to get to make questions. 01:35:08.910 --> 01:35:18.610 The codec that was demonstrated earlier, you can do rock and roll, funk, with a lot of bass, and a yelling guy, and a very quiet dude with his band going. 01:35:19.030 --> 01:35:24.110 The band was really good to get that music, like, I don't know if codecs are 01:35:27.200 --> 01:35:34.280 nice for speech, but the way I see it, if you portrait test a codec, you see what they really sound like under all circumstances. 01:35:34.420 --> 01:35:37.460 Because not all speech is perfect. 01:35:37.460 --> 01:35:43.240 So if you portrait test a codec, you get a clearer picture of what it really sounds like. 01:35:47.080 --> 01:35:48.480 Yeah, it's a good test. 01:35:48.480 --> 01:35:51.140 I know it's not designed for music, but there is music on hold. 01:35:51.340 --> 01:35:55.860 What happens when you're driving in your car, 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 --> 01:36:37.070 Calling in? 01:36:37.070 --> 01:36:37.730 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 --> 01:37:01.360 One, for all the color-ID speech and stuff you guys were talking about, 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 --> 01:37:13.280 Yeah, your standard VoIP call, even with MULA, 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 --> 01:39:23.870 For the most part, Asterisk is about as secure as a regular telephone, 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 --> 01:39:31.310 Cool. 01:39:31.310 --> 01:39:32.050 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 --> 01:40:14.820 The reason 01:40:39.610 --> 01:40:41.930 those payphones take an incredibly long time to call... 01:40:41.930 --> 01:40:42.510 Also, 01:40:46.950 --> 01:40:48.810 it works from my mobile phone. 01:40:48.970 --> 01:40:50.150 So it's not our... 01:40:50.150 --> 01:40:56.130 The other fun thing about the payphones out in the lobby 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 --> 01:41:11.730 However, thanks to Goldetel, whoever supports them, they have a very unincorrect standard on their payphones 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 --> 01:41:59.390 Sure, I'm broke. 01:41:59.390 --> 01:42:00.350 I'll accept the money. 01:42:00.810 --> 01:42:01.430 You won't pay me. 01:42:01.430 --> 01:42:02.410 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 --> 01:42:50.520 Yeah. 01:42:50.620 --> 01:43:02.240 Actually, you can set a password for this, but for convenience, since none of you from the outside world can dial on our Dundee plan, we figured it would just be easier if we could just answer the question 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 --> 01:43:07.660 Yes. 01:43:07.860 --> 01:43:09.040 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 --> 01:43:58.930 7920? 01:43:58.930 --> 01:44:00.570 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 --> 01:44:16.010 I have a nice Bluetooth headset. 01:44:16.010 --> 01:44:17.550 I have Wi-Fi hotspot. 01:44:17.550 --> 01:44:18.450 It comes right in hand. 01:44:18.450 --> 01:44:19.970 We've got to go wrap this up. 01:44:20.010 --> 01:44:21.330 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 --> 01:44:29.190 Anything else? 01:44:29.450 --> 01:44:30.530 Oldschoolfreak.com. 01:44:30.530 --> 01:44:32.950 We have stickers that we can give people. 01:44:32.950 --> 01:44:34.010 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 --> 01:44:38.630 Hang on just a second. 01:44:38.630 --> 01:44:47.190 You can also, before you go, if you have any questions and you can't get to us directly, 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.
