I have had VOIP internet phne service for about a year. It is VErizon, and has had it's problems.
Last week I subscribed to SunRocket VOIP service www.sunrocket.com (http://www.sunrocket.com)
In 5 days I received the modem, a free GE 5.8 2 station phone, and all wires. After attaching it to my WAN line it was working in 5 minutes!!!
NO issues, no time spent configuring the system, just perfect dial tone and voice service.
$199.00 per year, UNLIMITED calling, USA, Canada, and PR, with all calling features, ring tones etc!!!! At about $16.90 per month this is the deal.
FYI u need a high speed net connection that is NOT DSL to make this work, and the modem can be taken with you around the world and plugged in for your local area code dialing. MOst area codes are available.
I have IGONET, and have one in CA and another at the Havasu house. People always inquire as to how I have an 805 number in Havasu
