Hi, Chen-Che!
Are you sure it is a parsing problem? Do you see any errors in the logs?
Because my assumption is that your problem is in RTPProxy since (if I
remember correctly) it does not know how to handle port 0 sessions.

Dear all,
I encountered an issue as follows. I used two VoIP apps to make call with a
polycom phone that accepts voice calls only.
When the INVITE request from the VoIP has video descriptions in SDP, the
OpenSIPS SIP server fails to parse the SDP
of the 200 OK from the polycom phone. If the INVITE request contains only
the audio description in SDP, the OpenSIPS SIP server can run
rtpproxy_offer("oc", IP) successfully on the SDP of the 200 OK from the
polycom phone. It ``seems'' that the OpenSIPS server has problem with
processing the video port being equal to 0 in SDP.
The attached pcap file contains the above cases. Please help to clarify this
issue. Sincerely appreciate any help.
