Voice Over IP Goes Global, The DNS Way 193

awehttam writes "A couple of geeks have setup a non-profit public DNS root designed to map phone numbers to Internet protocols. These days we're hearing lots about Skype, and Voice over IP. Asterisk - the open source PBX - is nearing its version 1.00 release, Free World Dialup has applied to run the .tel top level domain, Good old Bell's are migrating to native IP, private sector layer 2 clearing houses are exchanging bits between companies the like of Packet8, China Telecom, MIT and Harvard and even the various regulatory agencies are pondering just what to do about things. In the mean time, consumer SIP phones are dropping in price, and free and open source software is helping to drive a new generation of provide the services networks." Read on for more.

"You just knew the other shoe had to drop. let's people register their existing phone numbers, and aim various services including VoIP towards a URL on the Internet. Now you can have your calls sent to your Free World Dialup account, or routed to your home Asterisk PBX instead, possibly where you have a $20 card attached to your phone line letting you make and receive calls through both your regular phone line and the Internet. isn't just about VoIP though, it can also map phone numbers to Email addresses, Instant Messager URL's, or any other protocol that fits in the "foo://bar" scheme of the 'net. :)"

      A group of my friends have a Teamspeak server set up (on my cable line) and we leave it going 24/7 so anyone can join when they like and see if anyone else is around; typically if we are not on TS, we don't wont to be bothered or can be 'knocked' by IM.

      Teamspeak is more like IRC in that you can have lots of people on channel at the same time. Its really reliable too, our uptime record on a dodgey old 350Mhz SuSE box is 64days - only interrupted by a blown PSU.

      I'm a little baffeled as to why skype was even mentioned. It completely different and not at all compatible with everything else listed. It's not "phone over internet" even though the authors of skype imply that it is. There is no PSTN connection anywhere. VoIP has certain stadards such as SIP, H.323, etc that are designed to interoperate and pass real phone calls over an IP network. Skype is proprietary and only talks to skype. Ditto with Teamspeak. It's not that they're bad, but they are not IP Telephony.

      I know you were joking, but I recently decied to try out Vonage []. With a cable connection you cant even tell its using the internet, and the ability to get a real phone number anywhere (well, almost) in the US beats a landline hands down.

      After 2 weeks with it, I've decided I'm going to drop my landline.
      • Thanks for the info. I must admit I'm starting to hear more and more positive stories about VOIP. Its certainly picking up in Europe and I have met engineers who assured me that in practice it can work really well. One pointed out that the quality seems much better than mobile phones and we don't complain about them too often.

        Those Tariffs are interesting 2c / minute is seriously cheap. If I was living across the pond I think I could be tempted.

      • We have Vonage at our office, and while it saves a lot of money on calls (especially to Taiwan, which we call a lot, but we use it for our long distance U.S. calls too), we don't feel that it's good enough to drop out landline.

        Don't get me wrong, I think Vonage is great, and I really like the service - just that sometimes it will break up, or give us strange echos, or other things.

        The Vonage MTA is connected straight to our DSL router (I don't remember the brand), on our SBC DSL line. There's no firewall
        • Your DSL router is probably NAT.

          I would recommend setting up a Linux (or OpenBSD) box with three ethernet cards such that eth0 is your internal network, eth1 is your vonage box, and eth2 is the WAN. Then configure iptables/pf to drop packets on the eth0eth2 route when the eth1eth2 route is "full". This is called QoS, I'm sure there are some nice HOWTOs that will help with this.
          • The DSL router is not running NAT. NAT was turned off in the router explicitly for two reasons:
            1. We have five static IPs (we're using business class DSL), and the MTA is configured with one of those static IPs.
            2. If I was using NAT with the MTA (a Motorola device), then I'd have to forward a few ports (the manual for the Motorola MTA mentions this).

    I was thinking about this the earlier today, and since it is relevant to this story I thought I would post it.

    Currently Skype is a computer to computer only program, but I have an idea to make it somewhat better.

    At signup each user should put in his local calling area/country codes whatever they all are.

    Then each user has the option of donating his phone line by hooking up his modem to the phone cord.

    Whenever someone wants to call a phone number they could try Skype, or a similar program, and the Skype network would then go search for any available modems in that area code. If there is one then your call would be sent over the net to that computer, and out on his modem.

    Now obviously this is a pretty generous donation on the part of the users. There fore there would have to be controls given to the user such as only allow people to call through your line if they are sharing their line. And there needs to be a polite "get off my phone I need it" button for when a Skype user is using your phone and you need it. Something like a message interrupting the call saying "the host modem owner want to use his phone line, please end your call in 30 seconds or it will be disconnected for you."

    And if there are no modems available in the area code you wish, you will get a message telling you so.

    I think this is would be a nice way of getting around long distance even to people who don't own a computer and/or use Skype.

    Are there any technical problems with routing audio info taken from the internet into the modem in the computer without the host having to listen to it over his speakers?

    What do you guys think?

      You'd need a PBX with a FXO card to transmit voice over a regular phone line.
      • um... I can transmit voice over my phone line with my modem by simply using the microphone on my computer. I have done this before, even my old compaq from...1996 had this capability in it's 33.6 modem.

        What am I missing here? Instead of having the modem use the mic input it could use an audio signal that your computer took off the internet.

        • Two things:

          1) The AT standard for voice is half-duplex: it can't listen and play at the same time. That won't work for a PBX.

          2) There are plenty of softmodems that can do full-duplex voice. However, their API's are not documented, and therefore are not supported.

          An X100P [] or an FXO module [] for the TDM400P [], in fact, are little different than a normal softmodem: they just have documented API's for dealing with voice. And, of course, buying the products from Digium [] helps support the people who make al

      • well obviously some encryption could be used until the last possible second before offloading it to the modem.

        If that turns out not to be possible, you wouldnt use this for a call that required privacy. If that is the case it sounds like paying long distance would be worth it for the privacy that you want. therefore you wouldnt even be in the market for this use.
        • Encryption? How? The attack described is against the analog line, after the call leaves the computer. At that point there is nothing you can do to protect the signal, you are trusting the person providing the modem to be a good guy.

That makes connecting to the PSTN a rather questionable idea though I have heard some talk about this from the phone companies recently. I wonder how the encryption issue will be handled. Anyhow, if you want a replacement for PGPFone without the debilitating lag try Skype. The audio quality is also much better.

    Yeah, VOIP is big- but at the moment, let's face it, the name sucks.

    I mean... VOIP? Try discussing that in a bar or in a non-technical environment. No, seriously, go try it: how do you even pronounce VOIP? I guarantee that you'll get laughed at, or stares at the very least.

    Therefore, I suggest that we replace Voice Over IP with Talking Over The Internet, or TOTI. Think about it!

    Instead of discussing VOIP down the pub, you can talk about the latest TOTI that you saw Samsung introduce. Or ask if your fellow geek has checked out the new TOTI down at the phone store. Or if you see a nice looking young lady (or man!) in town, you can whistle and challenge those around you to check out that TOTI.

    You see? It's perfect. Sure, it isn't as descriptive as VOIP, but it gets across the main idea, kind of. I mean, yeah, there's going to be the odd pedant that will contest the change, but don't listen to them- they're probably a taxman in real life or something.

    As with anything running over the public Internet, there will, at times, be issues which cause disruptions in service; ie. a M$ worm sucking bandwidth, neighbor downloading lots of pr0n and slowing down your cable modem connection, etc.

    The key to voice quality with VoIP is latency. Most VoIP endpoints have a built in jitter buffer which is able to recover from some latency, usually around 3ms, but after that is begins to be difficult to carry on a conversation. The latency here is the latency between you and the provider's media gateway, such as an Asterisk box. Normally if you have less than 50ms of latency, then you'll notice no degradation in call quality. If you begin to have more latency, the quality of the call will begin to drop off.

    I've been using Nuvio [] for almost 6 months and it rocks! Latency on my cable modem is around 30ms back to their servers so I rarely, if ever, have a quality issue. Their web interface is pretty cool and they do some cool stuff you can do with regard to voicemail and e-mail. Plus it's not PC based, just plug your regular phone into the adaptor they send you and you can take your adaptor with you when you travel, plug it into any broadband connection and still make and receive calls just like you never left home. This is pretty cool because I travel a lot and if the hotel has broadband in the room, it works great. I even have a few virtual phone numbers across the country so people I know in those cities can call me for free.

    As someone mentioned before, it's a lot like cell phones. You just have to look at what you're getting and decide if it's right for you. If you'd rather pay less than with a regular phone provider and be able to make TONS of long distance calls where an occasional dropped call is ok, then go sign up with Nuvio []. It's really as good as the reception is with a cell phone, and most of the time lots better. It all depends on the latency.

      Unless they are replaced by fiber to the home, or so. But that costs so much that rarely anyone is doing it.

    Disclaimer: I'm a partner in a Linux and Asterisk based VoIP startup in Norway.

    Thanks to efforts like, one day phone calls will be just another service running on the Internet. There will be no fees for doing simple peer-to-peer connections (me calling you to say hi), however special content and services will still have fees. Gateways to POTS* will be one such service for the foreseeable future.

    What this means is that we're in for a revolution. We're rapidly moving from a model where the Internet is run over phone lines to where the phones are run over the Internet. IOW, basic communications go from a metered service produced by a relatively small group of very lucrative companies, some of which are still state-owned monopolies, to the Internet model which we all know: A basically cooperative network where people purchase the bandwidth they need and agree to connect to their neighbours in order to join the big network. As I'm sure you've already figured, selling that bandwidth will still be big business, but nowhere near as lucrative as selling metered service.

    The big thing to get here is that the production of value, i.e. stuff that people are willing to pay for, will move from the center of the network to the edges. That is, from the big (sometimes monopolistic) phone companies to you and me. Welcome to the Internet revolution, you thought it was mostly over but in reality it's just starting. Oh, and if you thought the RIAA was running scared, they have nothing to fear compared to the big ol' phone companies.

    So what do I mean by "one down, one to go"? Two things, actually. First, e164 directory services are the first step, the second involves VoIP providers creating an environment where they can exchange traffic and get paid for services they provide to other providers. Say a user on your VoIP provider in the US calls a POTS number in Norway via a VoIP provider in that country with a POTS gateway. Peering the actual voice traffic is just one part of the exchange, peering the business end of things is the other. But this too will fall into place, sooner rather than later.

    The other thing I'm thinking of as "one to go" is TV. Today most countries are building separate infrastructures running parallell carrying different services: Voice over phone lines, TV over cable or OTA** and Internet over whatever's available. I'll give you an example:

    In Norway the Storting (Parliament) has decided to spend $0.5 billion to build an OTA infrastructure to transmit digital TV signals. Once the new network is in place, the old analog network will be switched off. And you thought the US digital TV mandate was bad...

    My prediction is that before the new digital TV network is in place it will already by severly outdated, completely overrun by the Internet revolution.

    The world is rapidly becoming digital and the Internet is the enabler. There is no future in building any kind of infrastructure unless it is dedicated to carrying Internet traffic. Wired, wireless, optical, satellite, it just doesn't matter as long as it moves the bits.

    Welcome to the revolution, we're just starting.

    * POTS: Plain Old Telephone System
    ** OTA: Over The Air, traditional broadcasting

    • Not trying to be picky, but the VOIP thingy, with asterisk, and all others, are still not qualified to be called a "revolution"

      A revolution means Industry B replaces Industry A, just like the cars replacing the horse-buggies.

      No matter how the VOIP progress, at least in the short term, will NOT replace POTS. This means, two industries will exist side by side, with some bridges in between the two camps.

      This scenario is much like the toothbrush and toothpaste symbiosys - without one, you don't need

    Don't any of you really understand what is? It's an ALTERNATE ROOT SERVER. That's right, folks, this is just like someone saying that they have a good solution to the .com name problems - they'll just start up their OWN .com root server and have everyone point to it! Then, you can get whatever domain name you want!!! long as everyone points to that root server. We've been here before - don't any of you remember? is the "real" root zone that is trying to replace. There are good reasons for wanting an faster/better/more clueful interface to ENUM, because is clogged with political sewage. However, I would want to see an organization with a little more clout behind them before I'd ever consider putting any time or money into an alternate root service; don't be surprised if suddenly you see a "cost recovery" (cough, cough, , cough) charge for usage.

From what I've read SIP phones actually use a combination of SIP to initiate sessions and RTP to move the actual voice data, but no straight "yes, it is" or "no, it isn't" answer on whether encryption is supported or not.
