=============================
All it took was to enable STUN on the Obi.
The Localphone account successfully registered right up on SP1
Placed a call to UAL Auto voice response 800 #. It works as normal. 2way audio.
Called a normal number via the GV web interface call button, still fine.
Had a friend call me from outside line. Answered the phone and it works.
The only problem is using a free DID from Ipkall and going GV>ipkall>localphone SIP>Obi, the incoming caller id shows as 206-682-0185 for everything.
Oh well, just experimenting for now but at least it does work.
Did not even have to mess with the port forward thing.
