I have two locations and I am testing the following
- Sip trunk between them
Both locations have a CCM of 4.1.3
Both locations are connected via a VPN tunnel
--- The Tunnel is set to allow traffic from both voice networks. it is setup to allow tcp/up (all ports)
I created the sip trunk in ccm on both servers. I created the CCS and route pattern to test between both sides.
I can call each side, it answers. But I cannot hear any voice
I can hear DTMF tones when pressed but no audio.
I also see some werid issues with call hold and stuff but i am assuming thats the Limited SIP compat in the verison of call manager
