Hello,
for nat trversal, I suggest you use the default kamailio.cfg from later
versions 3.3.x or upcoming 4.0. Read the comments at the top of the file
-- practically the routing logic for nat traversal is surrounded by
WITH_NAT define.
o= line is not used for rtp relaying, but some clients expect to be the
same as c=, at that moment it should be rewritten (or better rewrite it
always to be sure that is not the reason of some no-audio problem).
Cheers,
Daniel

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 ?
