@Anyone,
I finally have out-going calls working with VoipBuster thanks to Kwag.

The sound quality is great and the cost is free

I'm now trying
to get free/cheap in-coming calls on the same line. Here's my options:
1) Asterick@Home using IPKall (Washington DC numbers). This involves
using AAH as PBX and IPKall to redirect the in-comming call to a
Wash. DC number (area code 360-xxx-xxxx). This cost the caller $.
2) Callcentric has a pay-per-call plan. You sign-up for an account,
deposit $5, and calls per minute in US are 2 cent. Then
pay for a virtual phone number at $6 monthly. They have phone
numbers in my area (215, 267, 610, etc.). I like this flexiable
plan, but sound quality is not known.

BTW, all their plans
have caller id, call waiting, call block, and more.
If anyone has some suggestions and/or comments feel free to post
