I live in McAllen, Texas, USA. Vonage and Lingo cannot yet offer a local toll free number, so it was important that my SBC number be ported. Packet8 could not only port my SBC number, but they offered a local temparary number that could be called from the McAllen area toll free. I ruled out RoadRunner (Time Warner Cable) by price alone ($39.95/month).
I signed up with Packet8 on March 7, 2005 at $19.95/month. I faxed my application to have my SBC number ported to my Packet8 account on March8, 2005. I received my Packet8 device, hooked it up, and activated it on March 17, 2005. My old SBC phone number was ported on April 8, 2005. The transfer was almost seamless (a phone call to Packet8) when my SBC service was terminated.
So far, everything seems to be working as advertised. Call forwarding, Call waiting, Caller ID, Voicemail, Etc. Also, my use history is available on the Packet8 site and is impacted within 10 seconds of my hanging up the phone.
Quality of the voice is as good as my experience with SBC. I wear hearing aids and voice quality is important.
So far, so good. Time will tell..
