No audio ext-ext dialing....

[pacpac]

Hi, I get no audio either way when dialing extension to extension. Outbound through VoIP provider and Inbound via Direct SIP works just fine. I have 3CX on a dedicated server with Static IP and turned off STUN, and a PAP2T connected to 3CX (STUN disabled). Any ideas how I can get audio on extension-extension?

For the moment it is solved, had to untick 'Supports Re-Invite' and 'Support 'Replaces' Header' on each extension, I do now have audio when dialing extension to extension. Ref, my earlier post http://www.3cx.com/forums/support-replaces-header-and-supports-re-invite-25297.html

Thanks, use only one local subnet on the server, 255.255.255.255, and one subnet on the LAN where the PAP2T is connected, 255.255.255.0.
