Hi,

We’re currently using Kamailio 4.4.1 with RTPENGINE and one of our clients is sending an INVITE with two c params in the SDP, one in the Session Description, one in the Media Description.

When Kamailio contacts RTPENGINE to request a port, only the IP (c param) in the Media Description is changed.

The next hop, which is a Freeswitch, in turn sends the RTP stream to the IP in the Session Description.

Has anyone experienced this behavior? Is it possible to change both IP (c param) in the Session and Media Description?

Regards,

Grant
