Popular Telephony and Global IP Sound

October 13, 2004

Popular Telephony and Global IP Sound have announced a partnernership to provide best-in-class voice quality on Peerio 444 serverless softphone. I've used Global IP Sound's GIPS codecs and they are very impressive. I gave Global IP Sound a glowing review in a TMC Labs writeup last year, which you can see here: Global IP Sound TMC Labs Review

We found that the Global IP Sound codec had some pretty interesting positive effects under high packet loss conditions, which we tested using the Shunra Cloud 4.0 network emulator tool which can inject latency and packet loss. I should note that we used an older/slower PocketPC with a softphone client containing the GIPS codec engine, so the latency numbers are much higher than a PC or hardphone would have.

Vonage E911 news

October 12, 2004

Thought I'd share this news about Vonage and E911 using Intrado. As you know, one of the knocks against VoIP is 911 support in the event of emergencies. Of course, I have heard from a few people in the VoIP industry "knocking" against using Intrado's database. It could be due to the price-tag of using Intrado's database or it can simply be the people in the VoIP industry knocking them since don't have E911 support themselves.

AT&T CallVantage Behind Router

October 12, 2004

One of the knocks against AT&T CallVantage was that it doesn't work behind your existing home router/firewall. Their nemesis, Vonage, is able to handle being behind or in front of a firewall - a huge competitive advantage, especially for the security-conscious techies that don't like having any device in the front of the firewall.

Well, Andy Abramson brought to my attention that this is no longer the case - AT&T CallVantage does indeed support being connected behind a firewall, as confirmed by this AT&T CallVantage How To link: AT&T CallVantage

Though I did read somewhere else that contradicts this and it stated that AT&T DOES NOT support having the telephone adaptor (TA) behind the router/firewall, but that they "will soon support such a configuration".

I guess AT&T is moving so fast to add features and functionality to CallVantage the left hand doesn't know what the right hand is doing!

VoiceEclipse New VoIP Service Provider

October 11, 2004

Yet another Vonage-wannabe I recently discovered. They have a $29.95 unlimited plan with 2 phone numbers included (at least that is unique).

They also offer $12.95 for 1 phone number and 500 minutes and $24.95 for 2 phone numbers and 1000 minutes.

When I clicked the About Us link it said:
StarNet, Inc., founded in 1994 by Chief Executive Officer Russ Intravartolo, is a leading provider of dial-up Internet access and related products and services in North America. Through its state-of-the-art, fully owned MegaPOP network, StarNet provides reliable, high quality services designed to serve the consumer markets and the small to medium-sized ISP.

AT&T and LinkSys VoIP deal

October 11, 2004

It came as no surprise to me that AT&T and LinkSys would ink a deal to offer AT&T CallVantage on Linksys's home broadband router product line. Now, LinkSys has special VoIP customization for Vonage, AT&T CallVantage, and Verizon VoiceWing.

The Ethernet version is currently available directly from AT&T, and Linksys expects that all versions will be available at retail outlets such as Best Buy, Circuit City, Staples, and Office Depot later this month.

I hope the packaging is clear which VoIP provider you are getting when you buy it at a retail store (such as a Best Buy or CompUSA.) It would really suck if you planned on signing up with one VoIP provider but bought a LinkSys model with a different VoIP service provider embedded inside.
