I just have to pass this along.

Long distance VOIP for $20 a year and you can use your phone with it or use a headset. It has call waiting, caller id, call forwarding, voice mail, voice mail sent to your email, 911 and everything.
I have been using it and it works great.
When I bought mine, they had a 5 year offer for $100 at checkout time. At the time they said "free International calls" on the 5 year offer. They don't have free International calls and you have to buy credits for that. I gave them a lot of grief over this and I do not know if they changed it so it wasn't misleading. Their International rates are about like Vonage, 1010987 or AT&T International plan.
Other than that, it works great and I have had no problems.
Skype is still the best deal to place International calls.
The cheap International prepaid cards you find online are a ripoff and have very bad connection quality. Skype is as good a quality as AT&T in my experience.
