Hi All,

Looking for some debugging tips and comments on what might be causing
the media port in the 200OK ( Answer message) to be set to 0 by
freeswitch. Essentially it looks like data might be getting trampled
somehow.

Portion of 200OK going into Freeswitch
m=audio 16416 RTP/AVP 18 100 101..a=rtpmap:18 G729a/8000..a=rtpmap:100
NSE/8000..a=
fmtp:100 192-193..a=rtpmap:101 telephone-event/8000..a=fmtp:101
0-15..a=ptime:20..a=sendrecv..

Portion of 200OK coming out of Freeswitch
m=audio 0 RTP/AVP 96 100 101..a=rtpmap:96 G729a/8000..a=rtpmap:100
NSE/8000..a=fmtp:100 192-193..a=rtpmap:101 telephone-event
/8000..a=fmtp:101 0-15..

Note the media port has been set to 0 and the rtpmap for G729 is also
not correct. On receipt of this bad 200Ok the originator sends a BYE.

We are using FS as a B2BUA with bypass_media set to true. Thus IMHO
Freeswitch should not be touching the SDP portion of the message and
just passing it through.

This can reproduce this at will, so I can collect whatever data is
nessicary. I have added the sofia debug from the console.

Thanks,
