Message: sdp is in invite and 200 ok. the thing is, nearly the same config still worked in 1.2-branch, but after an upgrade to 1.4 it stopped.
it happens always, no matter if the callee or caller does the reinvite.
the following trace shows what happens. the rtpproxy-port in invite and reply is 41324. they must differ as they are used for different media-streams.

Message: do you have a SIP trace? Is it maybe related to late offer (SDP in 200 OK and ACK)? Does the bug happens always or only if the reINVITE is sent by the callee?

Comment By: Nobody/Anonymous (nobody) Date: 2009-06-30 16:15
Message: in detail, the sdp is rewritten with the wrong port for this direction of the session. it's the same as the answer's which does not work. to build the query for the rtp-proxy from- and to-tag the have to be reversed in this case.
