Voice Over IP Goes Global, The DNS Way
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. E164.org 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. E164.org 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. :)"
could this be the end of long distance charges?

Does this mean that just when I figured out how to whistle at 2600 hertz, it's become useless? ;)
"What do you think?" "I think 'What, do you think?!'"
Personally, I prefer TeamSpeak to Skype. The interface isn't quite as nice, but for group conversations it works alot better (IMO). Less bandwidth too, which is better if you're using it for VoIP while gaming..
Obviously we are in the beginning stages of something very large. Telecom as we know it today will change... it's only a matter of time.

Thanks, I've already linked most of those sites and the only useful info I get is that there's a cheaper Asterisk compatible card out now. :( How about a bit more info on how these different methods actually stack up against each other? Maybe some success stories?

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?
I've been using vonage.com for my primary home line and fax line for a while now and I absolutely love it. Not only can one talk a lot more for a lot less money, the other features that are included are remarkably useful. I love transferring calls from my home phone to my cell phone before I walk out the door, and I'm planning to put together some code that interacts with Vonage's web "dashboard" to allow better integration with the rest of my digital life.
Marrying phones and computers in the home is going to open a whole new avenue of technical exploration, and unfortunately, exploitation as well..

Not that I dont have my own gripes about acrobat, mainly the fact that it takes forever to load up the full version or even just the plugin. And I have an Athlon XP 3200+!
Even longer since I switched to Firefox, though that might just be my imaginatin.
When I play and use voice comm, I use Ventrilo. When I (or some of my colleagues) work from home, we use Ventrilo to conference, it works very well!
Ventrilo is also free.
Any technology distinguishable from magic, is insufficiently advanced.
Why do you call the Voice Peering Fabric a "clearinghouse"? By functionality, it is clearly a "peering center" and not a clearing house.
Maybe less fancy and more clarity would improve the eloquence of the posts...
if we end up relying on making phone calls via the internet, what's to stop the next killer virus knocking out our phone 'lines'?
Asterisk is an awesome piece of code. They have presented at several hacker cons in the South East (Phreaknic, Interz0ne), and I have been quite impressed. Most PBXs handle things like T1 frame generation, TDM, switching, etc in hardware. Asterisk does it all in software using Linux
I'm afraid telcos are letting their legal departments burn the midnight oil in patenting anything obvious and even remotely related to this.
The combination of two obvious technologies (telephony and TCP/IP) should not be patentable.
We'll see how this turn out.
The various Linux telephony projects being mentioned left and right are hopeful developments.
Now that (soon to be "legacy") regelar phone networks are being migrated to TCP/IP, I think the time has really come to finally seriously start making the switch to ipv6.
"Oooh, does that mean we get to kick some puffy white mad zionist butt?"
Teamspeak is great!
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.
Ripping an new rectum in the fabric of spacetime.
I've been using Packet8.net for my telephone service for about a half a year now, and I've been thoroughly impressed. For 20 dollars a month, I get completely unlimited long distance, call waiting, voice mail.
There are a few glitches every now and then. Somedays it won't let my calls go through, but usually my voice mail bails me out. It's just as reliable as a cell phone, and much much cheaper.
CAPS LOCK IS CRUISE CONTROL FOR COOL!!
may I ask why? ...mainly the fact that it takes forever to load up the full version or even just the plugin.
You just answered your own question, and that's why I'd like a heads up. Then I can download it for my perusal at a more convenient time. When I'm expecting a pdf, I don't mind the wait so much. Otherwise it looks like my machine locked up. There's no warning on how big the file is, and the time waiting for it to download(especially on dail-up) can be very distressing. I don't always catch the info in the status bar. And focusing on the tiny print there can be painful to the old eyes.
What?
Good design, lots of testing and before-the-fact protection. Just make sure the Anti-Virus Cartel doesn't get involved.

Expect to see legislation with some assinine label like "The VoIP pro competition rules". This will be of course a couple of millions lines of regulatory text that will be sold to the public as "deregulation".
What will this legislation accomplish? It will help the baby bells and large phone companies hold on to their market shares and stifle competition.
Jaded? Me ? Naaaaa, just experienceed with more than a decade of being told "We are for de-regulation" while signing bills that give the big guys even more. The FCC unep ruling recently is a perfect example of such double talk.

"Science is about ego as much as it is about discovery and truth " - I said it, so sue me.
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.
Oh ok, I thought maybe there was another reason that I wasn't aware of.
On this point I agree with you, infact my computer did lock up for more than a few seconds when I opened that pdf.
Is that adobe's fault or what? Seems like they have a knack for bloatware...
VoIP is very good competition for the POTS phone companies. Its funny now I see plans for $50/mo unlimited long distance. A few years ago I can remember a friend paying gigantic sums of money on long distance phone bills. Now for $50, its an all-you-can-eat buffet.

If you're not outraged, then you're not paying attention.
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.
If you think that the people behind e164.org are in it for the good cause, you're kidding yourself. There already is an official phone number to DNS tree: e164.arpa, as designated in RFC 2916. This is a fight for the root of _the_ registry of all POTS-number to VOIP/email/web mappings. There's money to be made, and lots of it.
VOX is an old term that covered any Voice Over type (ip, frame relay, atm, whatever) and it sounds cooler than voip or v,o,i,p.
That and I believe the machine puts itself on "hold" while the file is downloading. A 1 MB file can hold you up for over five minutes on dial-up. I just need to be more careful, and check the status bar. Won't be a problem then. :-)
What?
Someone should check out this new Bluephone! It is the ultimate VoIP package, u can use your cell over Wifi, 3G or GSM networks, probably the killer app for VoIP.
There's no way for the little guy to make any $ with it so it will be owned by the big corps forever. No, Asterisk is not the answer because, while it works, it is totally not a commercial product. And even if you productize Asterisk how do you sell it? Companies are not going to put their mission critical phones on some open source thing. Would you? (IT and telephony guys only please)
I was one of the first vonage customers since I was in a unique position where I lived in one country but worked and had a fiancee in the US.
Vonage worked out great since it gave me unlimited calls to colorado for a tiny fraction of the price i'd be paying to call internationally.
It had occasional problems, but given that I consumed about 3000 minutes in a high month, it worked great most of the time.
Currently i'm moving to freeworlddialup since everyone i talk to either has broadband or is local.
Picked up a SIP Phone Call-in-One and I've got to say, I'm really impressed. It does exactly what they say it'll do, it does it well and it does it cheap. Living in Madrid, until now, meant I was sort of cut off from my brother. Now, I call him whenever I want, talk as long as I want and it doesn't cost me anything other than the bandwidtch charges for the DSL connection that I was already paying. Definitely impressed.
Also, we've been using the SIP Minutes thing to make calls to Canada, Chile and and a couple of other countries - all to PSTN numbers - and we're really happy with the cost (cheap as dirt and no monthly fee or anything stupid like that), the sound quality and ease of use are excellent.
My only complaint is that they won't hurry up and set up Virtual Numbers. I'm thinking of starting a small business and being able to have a local number in Paris, NY, Toronto and Vancouver would really help me out. Having all of those numbers ring through to the same phone... beautiful.
Played a little with Skype (litterally, we were roleplaying and brought a friend in from another town) and I wasn't as generally impressed. Sound got wonky too often for my tastes although it could have been a bum mic.
Also, been toying around with this and I have to say this just makes my SIP Phone better. Friends from all over can call me, leave me a voice mail if I'm not there (which gets emailed to me of course) or, with this, I can (and have) set up some cool conference calls.
My mother has a SIP phone (actually, a SIP adapter) at home.
So does my uncle.
So does my little sister.
So do a half dozen friends (spread out over several countries in both hemispheres).
All these SIP devices connect to a very small linux box colocated in the US, running asterix (which is an excellent piece of software, btw).
Through that, I issued everyone an extension, voicemail, etc.
Further to that, anyone who wants an account at iaxtel, free world dialup, voicepulse, well, the asterix box can connect to those for them, and route calls to the appropriate extensions. It can also share the outgoing services (Which may violate some TOS, who knows) among all the users (or selected ones).
I can also use end-user phone systems as dialin/out lines, which does require some slightly different adapters.
My point?
VOIP is not a heavyweight thing. The only big scary part is locating the correct parties... this is where POTS works well.. because we have a global dialplan that everyone agrees to.
Eventually, everyone with any bandwidth will just HAVE phone service to each other, with some kind of globally understood dialplan beneath it (which will not be based on numbers at all) and links back to POTS will be fewer and rarer.
I would REALLY like to see a standard for finding phone numbers via DNS. We use DNS precisely because it's too hard to remember the correct up-to-date IP address of the services we want. Why should we continue to remember peoples' phone numbers? Now that many cell phones are internet-connected, you should be able to type in e.g. "call.joesmith.com" and the phone should do a DNS lookup to get the phone number.
Maybe this has been done already? Or is the "typing in" the problem?
of a service offering unlimited calling to the US & Canada (the Canada part being significant here) that will work with asterisk?
Hint: Packet8 and Vonage will not.
Hint: Voicepulse works great, but only has calling in the US.
TBH I'm surprised slashdot is so late with this...
:)
:)
VOIP rocks. I haven't even got my FXO yet (shipping from the US takes time) and I've already got my PBX configured with cheesy 'on hold' music so I can annoy everyone
From work I have X-Lite plugged into my server at home, so if I'm needed it's a free call. I've also got local dialup numbers the US, Germany, etc... real fun.
For now it's totally unreglated and largely free (if you don't count $16 for the FXO, and $50 for the phone).. I doubt it'll last, but let's use it while it's there
Here's an idea that me and a friend thought a bit about last year.
--
A little nonsense now and then is cherished by the wisest men. -Willy Wonka
its kinda funny 10 years ago you had to use p.o.t. service to get on the internet , now you'll be talking on your phone thru a i.p. proticol no phone lines need . I can see maybe in the next 10 years there might not be any phone lines left , and if they are it will be in those areas that are hard to reach with broad band now .
i have no sig
Thanks to efforts like E164.org, 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
And remember kids: Never trust a computer you can actually lift.
You'd lose your phone.
You think your ISP gets cranky about you running a server? If you did this, and the telco figured it out, (for example by looking for symmetric traffic on your internet line and your phone line, or by subscribing to the service themselves to get a list of numbers) they'd cut you off. Not many people will want to burn down their landline to give away phone calls.
Twenty some-odd years ago, a guy from my high school was caught running a demon dialer. Southwestern Bell explained to his parents that he could have either a live phoneline or a modem, but not both.
This is what I always wanted to do with VOIP too, but I could never convince myself that it was worth the risk.
I've heard that some companies with international networks and PBXs are illegally doing something very similar with VOIP, but only with their own calls. Their lines are expected to be heavily utilized, and they have much more leverage with the telcos.
Assembly is the reverse of disassembly.
VIP sounds pretty swanky to me.

Don't any of you really understand what e164.org 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!!! ...as long as everyone points to that root server. We've been here before - don't any of you remember?
e164.arpa is the "real" root zone that e164.org is trying to replace. There are good reasons for wanting an faster/better/more clueful interface to ENUM, because e164.arpa 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.
Without having read the article (this is slashdot after all), what's wrong with ENUM? That already provides phone# to location/service mapping via DNS...
Who's giving me odd that Digit networks paid for this story.
coz thats what im calling it
I was wondering how long it was going to take someone to set up a DDNS server for this purpose. About time.
I wrote a cool app which streams voice in between two IP addresses after having some bad experiences trying to get some of the more complex app's to work well, and thru a firewall correctly.
It's here...
It just uses one UDP port (51981), and works pretty well. Other things work well, but they require a service, like yahoo IM... and I like the software to be independent of any servers, and be lightweight enough to use in the background.
Not trying to be picky, but the VOIP thingy, with asterisk, e64.org 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 the other.
All I can see - and please correct me if I am wrong - is that VOIP will co-exist with POTS for quite some times, until the time where we have embedded communication devices on our shirts, or the back of our hands (much like some of the sci-fi flicks) and at that point, we might don't need both VOIP and POTS.
Muchas Gracias, Señor Edward Snowden !
Mod parent up: this is an important issue.
.com. The fact is, while any old joe can say that you should register your telephone number in their DNS zone, e164.arpa is the domain the RFC says to do it in. Having two such domains is to have two roots for this mapping, with the possibility of discrepancy between them. Surely that's significant enough for the editors to mention?
:-)
I'm disappointed the Slashdot editors didn't notice that e164.org is in essentially competition with e164.arpa; this is very important to understanding what e164.org is about. As the parent says, it's like Alternic or, to avoid the unfair comparison with Altnernic's business practices, New.net.
I don't accept my sibling post's claim that e164.org is not in competition with e164.arpa but is merely "supplementary": that's like saying ".travel" is "supplementary" to
PSTN-DNS mapping is not an easy topic. For example, how would you like someone else coming along and registering *your* phone number in an ENUM server (and so being able to receive SIP VoIP calls intended for you)? I'd be interested to hear how e164.org plan to prevent this.
And finally, VoIP is pronounced as a single syllable, with the vowel sound rhyming with "boy"
guys.. its great that i see you posting about USA and Canada. But VoIP is happening worldwide. It is a reality weather we want it or not. Most carriers are doing VoIP for ILD and we dont even know about it. I work for HablaNow (http://www.hablanow.com), a LatinAmerican VoIP provider, and i must tell you, what is most disturbing is the attitude of the governments down here and the problems deploying VoIP legally due to monopoly telco situations. All of this is changing wether they want it or not. Everybody's doing VoIP, from small cyber cafes, people using SkyPe, Asterisk, iptel, etc all the way to traditional carriers. There's no stopping for VoIP ;-)
voip rollout should be held up as a model of development in real world applications that allows for the customization of essentially blank template devices. a healthy mix of different ideas expressed in different languages, across varied platforms, and with extreme flexibility. downside? just what are we going to do with all that twisted pair?
Great stuff, now we can just expect MILLIONS of spam calls from China.
- Unregulated
- Dirt cheap
- Easy to script a 5 sec call to millions of numbers
I'm sorry if I haven't offended anyone
So, I tried to find anything you could use with a headset, ventrilo server? no problem, allthought client was Windows only. Skype? Only Windows and PocketPC. Teamspeak? Only Windows and Linux and required a lot of weird RPMs to be installed on my beautiful freebsd box so no thanks. So, the question is, are there anyones which actually is FREE and works? I don't care for this proprietarian(?) crap which only run on a single os.
I'm disappointed the Slashdot editors didn't notice that ...
you are new here, right ?
New things are always on the horizon
gah! it's slashdotted!
I have discovered a truly remarkable sig which this 120 chars is too small to contain.
I can't seem to find a good answer as to whether SIP phones support encryption or not. I don't feel too terribly comfortable with transmitting my voice conversations unencrypted over the net. 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.
