I need a sanity check if you don’t mind… I am setting up a stateless proxy for
several (separate, not load balanced) Asterisk servers behind Kamailio 4.2
(with domain and dispatcher). All works as expected except when called party
hangs up, as Asterisk seems to address the BYE “To” (that is sent to the
calling party) to the originating domain, and not the IP of the UA (as it does
in other cases). When this happens, stateless Kamailio does not seem to know
how to route them, which makes sense. I assume I would need to rewrite the
“To” field on BYE message so that it contains the UA’s IP (to match the BYE’s
that are routed correctly). The RURI header contains the IP/port of the UA, so
I am attempting to use it and here is where I am stuck…
Here is the subst from onreply_route:
if (is_method("BYE")) {
xlog("L_NOTICE", "BYE Detected \n");
subst('/^To:(.*)<sip:(.*)@(.*)>(.*)$/To:
<sip:\2@$rd:$rp>\4/ig');
}
Here is the “To”:
To: "Test User 2"
<sip:1...@zxcv.asdf.qwerty.net>;tag=8AB53900B9646F1DF05330E7FBF846C8
Any obvious glaring mistakes here? Would I then need additional logic to
forward the BYE on?
My apologies if this is wordy, or nonsensical...
