Conference Calls Wont Traverse My Trunk

My conference call wont go thru my SIP trunk. I may be missing a dialplan configuration setting as my PCM phone to phone calls go over the (GSM) tunk.

The server with the conference:
exten => 5777,1,GoTo(conf-confDemo,join,1)
[conf-confDemo]
exten => join,1,ConfBridge(confDemo/S/1)

The server from which some users dial in from:
exten => 5777,1,Dial(SIP/$EXTEN}@200_PBX)

Any insight appreciated.

Thanks,

Dado

  • Dado, subject sounds like a personal problem. Sorry couldn’t resist.

    How about some CLI debug info while trying a call?

  • The cogerence works but doesnt go over my trunk. Its bypassing and the codec is PCM of phone. But in phone to phone call, the rtp traverses the trunk and I capture gsm packets to verify.

    The sip debug for conf call setup and leave:
