Attached to Project - sip-router Summary - Some cases when rtp proxy not change port numbers in media Task Type - Bug Report Category - Core Status - Assigned Assigned To - Andrei Pelinescu-Onciul Operating System - Linux Severity - Low Priority - Normal Reported Version - 3.0 Due in Version - Undecided Due Date - Undecided Details - We use the rtp proxy and we have seen problems in some cases when rtp proxy should change port numbers for the media.
We have a sip-client which also send position information included in the INVITE. The problem seems to be that the rtp proxy cannot handle the INVITE when the header in parameter "boundary=" has the value between "". And it cannot handle if the body has the parameter "Content-Length:". It results with that the ports will not be changed.
May there is some modules which can solve this problem?
Here I give three cases with INVITE packets which one is handled fine by rtp proxy.
***** Case 1 - Handles fine by rtp proxy and changes port numbers *****
INVITE ... .... Geolocation: cid:123@sip.domain.com Geolocation-Routing: yes Content-Type: multipart/mixed;boundary=MessageBoundary

***** Case 2 - rtp proxy dont change the port numbers (problems with "" in boundary value?) *****
