I have made the switch to PhonePower as well... I also have intermittent not configured issues.
I have enabled syslog on the Obi100; immediately following a reboot the first REGISTER messages returns a 401 Unauthorized response from PhonePower yet my calls go through... wait a couple minutes or hours and the phone no longer works.
The current solution? Reboot Obi100. LAME!
Syslogd is listening to port# 514:
<145> Reboot is scheduled in 1 seconds

<144> Goodbye! Reboot Now. (reason: 4)

Also here is a snippet of what the logs show when you CANNOT MAKE OR RECEIVE INCOMING CALLS through PhonePower. I get the SIP/2.0 403 Forbidden error. Again the solution is reboot Obi100. LAME!
