My setup is SP1 only, obi100 registered to Sipsorcery to make GV calls. Sipsorcery register to CallCentric.
My cellular smartphone use Csipsimple to register to Sipsorcery as well,
I can see two registration bindings with different ports from Sipsorcery web.
I can make call and receive calls with smartphone (WIFI and wireless networks), everything is good.
When I answer in-bounding calls from obi100, everything is good.
When I make call from obi100 box to obitalk test, **9222222222, every is good.
When I make call from obi100 box to PSTN number. call is connected normally, DTMF works well, I can hear in-bound voice, but other party cannot hear my voice.
My router is old AT&T 2wire, tried to configure with firewall, no improvement.
If I set Obitalk STUN enabled, incoming call rings, but when I push answer button, call is not connected and still rings.
I am very confused. Thanks a lot for any suggestion and help.
