[OpenSIPS-Users] ignoring IP Connection Information

[Jorge Luis Ortea]

One question, by default, any INVITE request managed by OpenSIPS, it sends RTP flow to IP source signaling or IP (c=) in SDP ¿?
In this case OpenSIPS public interface is in the same network than SBC, no nat and OpenSIPS has not nat_traversal implemented.
When a INVITE is received from SBC with IP: 1.2.3.4 and with 'c=IN IP4 5.6.7.8' in SDP. Why is OpenSIPS sending RTP flow to 1.2.3.4 ? 


Very Thanks, Regards.

Hi all,

I am using OpenSIPS 1.8.2 + RTPProxy on bridge mode, I force a destination and a socket between 2 points:


            (public net)                                            (private net)
[SBC] ------------------->  [OpenSIPS+RTPProxy] -------------------> [PBX]


The signaling manage is right, but I have a problem with RTP flows. When SBC sends a INVITE, it has a IP Connection Information different from IP signaling however when the dialog begins [OpenSIPS+RTPProxy] sends RTP flow to IP signaling from SBC, ignoring IP Connection Information.

Must I do something to force RTP flow?  What can i do to solved it? 

Very Thanks, Regards.
