[Freeswitch-users] Media Not Heard When Bridging 2 Calls with same Gateway

Sun Aug 23 21:14:15 PDT 2009

If I understand your issue correctly, it sounds to me like FS is not
set to anchor the RTP media stream.  Experience suggests that most
SBC's do not like trying to loopback RTP traffic to themselves.

Check to see what IP address's are getting used in the
c=xxx.xxx.xxx.xxx for the INVITE and 200OK messages.  If you see the
SBC IP address in messages on both sides of the FS box this will be
your issue.

You could try setting bypass_media=false in your dialplan.
