Hi, I mistype. What I want to know is what affects Kamailio decision in rewriting c= in SDP.

In http://kamailio.org/docs/ser-getting-started/SER-GettingStarted.pdf, I see that

if (isflagset(6)) {

force_rport();

fix_nated_contact();

force_rtp_proxy();

}

Which means that Kamalio only cares if the caller is behind NAT or not.

Does it care about caller's symmetric NAT, using STUN, callee's nat type ?

Hi, I read in http://kamailio.org/docs/modules/1.4.x/nathelper.html that Kamailio might rewrite ip address in o= in SDP to facilitate NAT traversal.

It may decide to use to original IP or use IP of RTP server. What factors affect its decision ?
