I have PAP2T with Viatalk service.
Everything else works fine.
First call make my phone rings. Whe answered I can not hear anything (both ways). Call get disconnected after 20sec.
I place second call imidiately. Audio path is established this time.
When I use X-lite instead of PAP2T everything works fine.
When I connect PAP2T directly to my cable modem it does work on the first call.
Played with parameter includung stun server. Did not have much luck.
I tried configur static translation of port 5060 and did not see any difference.
My router is Cisco 806 but I tried Cisco 2811 - the same result.
Does anyone have something like that?
Am I missing something?
