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. :)"
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..
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..

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.
The FX100 module is a rebadged Intel Winmodem worth about $9.99. They're taking the p*ss wanting $100 for it.
Even the 'cheap' ones are expensive when you realize what they actually are... Altruism only gets you so far. If they wanted $30 I'd buy from them, but $100? No way.
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.
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"
