In the down time just to get ipkall direct inbound working. With a Zyxel wifi phone P2000W V1.
Software Version Wj.00.13
Bootrom Version B.00.16
Release Date May 12 2006
It works great. I had to forward ports 5060,2070 on my router, because it was a hit or miss with out port forwarding.

"In my experience, IPKall directly to my softphone is 7 hops while Gizmo5 is 12 hops and the first 4 hops is inside the ATT network so really its 3 hops from IPKall vs 8 from Gizmo5. That's a significant improvement going with the direct route. Of course your network path may be different. Also call quality will not be affected by Gizmo5 since it will not be touching their server."

This might be worth keeping, I use my ipkall number for GV. Better quality, and if the server is down, incoming calls still works.
Also the Registration hiccups drops the calls on the Zyxel.
Which will not happen routed this way.
