My CallVantage Service Is Working

Less than a week ago I signed up for a trial of AT&T's new CallVantage service.

Based on some initial calling I can only say that people on the other end have no clue I'm using VoIP until I tell them so. The call quality is as close to PSTN as I have heard to date. The set up was easy as easy can be, and most of all, it all worked as promised. There was no jitter, latency, rebuffering or packet loss that I could detect.

Candidly, I'm not surprised the service is this good. AT&T has too much to lose in putting out an inferior product. By putting out a product that is at basic mode already better than the competition which went first, AT&T has really fired a shot that will be heard around the telephony world.

I've had CallVantage since the Wednesday after Easter and love it. It's been trouble free except when they did there update on May 27th. The studder dial tone didn't work for a week but now it's fine. Has anyone else received an e mail inviting them to invite up to 20 people for a party and AT&T would pick up the bill? The e mail claims you pick the place and they will pick up the tab for up to $1,000.00

I was very impressed with ATT"s CallVantage.
It simply works. and works well!
When it came time to activate my TA (TELEPHONE ADAPTER, It failed to activate.
I t was my fault, I still had my phone cord from my wall jack in the computer.
I cannot believe I have finally been set free from the big behemoth of my local phone company.
