Bone,
We have used packet8.net for 2 years or so now. They are #2 right now behind vonage.
$20.00 per month gets you unlimited USA / Canada calling 24/7 Also, For our overseas ppl, I just send them the adapter and they have a local Gresham #
When I travel in europe I bring 1 adapter with me, plug it into any network and then I can just call like I was in Portland, or the wife can call me locally. works perfect.
Also, you can transfer your current #'s to them. Are you with Verizon??
Verizon Fios (fiber) is ready to roll soon in beaverton area I think. 15 meg down, 2 meg up, $49.00 per month
