[Freeswitch-users] Google talk no RTP connection

[Tor Petterson]

Hi

I am having a problem with establishing voice calls to Google talk.
>From the logs I can see that Freeswitch tries to tell google talk the
IP address and port to talk to but Google returns an error.
I have opened all RTP ports in my firewall and as far as I can see
Google never tries to access the RTP port
