Hello,<br>
<br>
looks like a broken routing logic somewhere. What addresses are
assigned to your server? There are some exposed or masked in the
trace you send, which of those are?<br>
<br>
Cheers,<br>

Hello,<br>
<br>
The configuration is:<br>
<br>
Jitsi #1 registered with sip2sip.info<br>
Jitsi #2 registered with my server(s) (Kamailio edge proxy and
Kamailio registrar) on Amazon AWS running Kamailio from git master<br>
<br>
I make a call from Jitsi #1 to Jitsi #2 (there are SRV records for
my domain in Amazon Route 53 so that sip2sip.info can find my
servers). The flow of the call is:<br>
<blockquote>Jitsi #1 -> sip2sip.info -> Kamailio edge proxy
-> Kamailio registrar -> Kamailio edge proxy -> Jitsi
#2<br>
</blockquote>
<br>
The calls do not get established properly because the ACK is not
correctly routed. Calls between two Jitsi instances registered on
my servers works. Calls from Jitsi #2 to Jitsi #1 (my servers to
sip2sip.info) also work. This problem occurs whatever the value
of the "enable_double_rr" modparam.<br>
<br>
The 200 OK (INVITE) sent from my servers back to sip2sip.info
looks OK and has a valid looking route-set:<br>

With debug turned up on the edge proxy I see the output from lines
673 and 723 indicating that the loose.c:after_strict() is run.<br>
<br>
My edge proxy configuration is:<br>
<blockquote>
<pre>request_route {
route(REQINIT);
route(OPTIONS);
sip_trace();
setflag(F_SIPTRACE);
if (is_method("CANCEL")) {
if (t_check_trans()) {
route(RELAY);
}
exit;
}
route(WITHINDLG);
...
route[WITHINDLG] {
if (has_totag()) {
if (!loose_route()) {
switch($rc) {
case -2:
send_reply("403", "Forbidden");
exit;
default:
if (is_method("ACK")) {
if ( t_check_trans() ) {
route(RELAY);
exit;
} else {
exit;
}
}
send_reply("404","Not Found");
}
} else {
if ($rc == 2) {
setflag(F_OB_DRIVEN);
}
if (is_method("NOTIFY")) {
record_route();
}
route(RELAY);
}
exit;
}
}
</pre>

Have I done something fundamentally stupid here, or is there some
obscure bug in the loose/strict routing code?<br>
