I initially setup 2 external extensions using Grandstreams which are located at different sites. Different firewalls. I'm able to call each other and answer but no audio. I then tested it with the 3CX Windows Softphone. Same issue. I tried different locations given it maybe a firewall issue still no audio.
If I use the 3CX Tunnel it works great. But the Grandstreams can't use it so not a solution. If I turn on "PBX Delivers Audio" for the extensions it works as well but this is less than idea. STUN is setup on the 3CX Softphones so this should work?
The server is setup 3CX v11 with latest updates. It has internal and external NIC's (different IP's). The firewall test completes successfully.
I've read many WiKi's on configuring the server and clients like adding the server as the outbound proxy. No joy. Any help would be appreciated.
