I recently moved from YAK VOIP to comwave because YAK new owner (poor
him) decided to abandan their VOIP service by end of 2006. I had been
using YAK for 2+ years I am very satisfied with their service and
pirce, many friends of mine are YAK customers as well.

The phone adapter (LINKSYS PAP2-NA) I received from YAK could not work
with comwave (no receiving, dial out only), althought I previously was
told that it would be fine for Comwave service Tech guy from comwave
worked with me (another tech guy) for more than 4 hours in remote
control session and did not find a solution. So they decided to send me
another iphone adapter (50$ + 12$ shipping).

Two days later I called home from my office as attempt, it suprised me
that call receiving was working well. (I did not make any
changes/reboot). So I called comwave to stop sending me the new iphone
adapter. But I am not sure this will last forever or just by accident.
