[OpenSIPS-Users] Unable to parse SDP when processing 200 OK from pure-audio polycom phone

[Răzvan Crainea]

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.
