force_rport() doesnt do the trick - it was one of the first things i tried :-) All it seems to do is add 'rport=...' to the Via line on the returned message, not actually *send* to that port. Its clearly something ridiculously basic. Also, fix_nated_contact() doesnt work entirely either. What it *does* do is ensure that the NOTIFY (from the Sbc to the fone) goes to $sp: $si...
Incidentally, if i stick a t_newtran()/t_release around my REGISTER handling section, i get the same behavior, i.e., the responses go to 5060 instead of the source port (i *am* using force_rport() there). Is that a Clue?
cheers
p.s.
The difference i see is as follows
A) Using the following basic code, the response (i've omitted most of the message)
if (!t_newtran()) { sl_reply_error(); return(-1); };
if (is_method("SUBSCRIBE")) { handle_subscribe(); t_release(); };
U 2009/05/28 05:56:44.260579 1.2.3.4:2352 -> 5.6.7.8:5060 SUBSCRIBE sip:mm1@5.6.7.8 SIP/2.0. Via: SIP/2.0/UDP 10.0.0.10:5060;branch=z9hG4bK537dd37BF6A3AE6. Contact: sip:mm1@10.0.0.10:5060.

B) If I use force_rport(), as follows, I get
if (is_method("SUBSCRIBE")) { force_rport(); handle_subscribe(); t_release(); };
U 2009/05/28 05:56:44.264687 5.6.7.8:5060 -> 1.2.3.4:5060 SIP/2.0 202 OK. Via: SIP/2.0/UDP 10.16.0.168 :5060;branch=z9hG4bK537dd37BF6A3AE6;rport=2352;received=1.2.3.4.

I assume you mean "the response gets sent...", right?
Any ideas? Should I be doing something with nat_traversal.co (don't see what, but worth asking...)
The relevant portion of kamailio.cfg is
Add "force_rport()" here.
if (!t_newtran()) { sl_reply_error(); return(-1); };
if (is_method("SUBSCRIBE")) { handle_subscribe(); t_release(); };-- Iñaki Baz Castillo ibc@aliax.net
