Hello,
is the ip 10.0.0.40 set as alias or domain in domain table? It looks like kamailio considers it to be a local domain.
Cheers, Daniel

Hello,
I have the following setup:
UAC (Bria) ------ Kamailio -------- Freeswitch
Kamailio is used to authenticate the client using basic authentication.
Upon authentication the INVITE is sent to Freeswitch for further handling.
Kamailio stays in the path using record-route.
At this point, the authentication and calling FS works fine.
For now, FS just answers, plays a file and hangsup the call.
Answering the call and playing a file works fine.
When FS hangs up the call, the BYE message is sent back to Kamailio.
The problem is the BYE message from FS contains a Route header which points to Kamailio again.
Which causes Kamailio to send the BYE message back to itself. Kamailio then replies with a 404.
The BYE is never sent to the UAC.
When I remove the record_route() for INVITEs, the call works fine, but Kamailio isn’t kept in the signaling path.
The BYE is sent directly to the UAC.

Here is the WITHINDLG route:
route[WITHINDLG] {
xlog("L_INFO", "[R-ROUTE-WITHINDLG:$ci] !>""Route:WITHINDLG;UnixTime:$TV(un);RequestURI:$rU;RequestMethod:$rm;FromTag:$ft;ToTag:$tt;CallID:$ci;From:$fU;To:$rU\r\n");
if (!has_totag()) { return; } # Sequential request within a dialog should take thepath determined by record-routing
if (loose_route()) { route(RELAY); exit; } else { if (is_method("ACK")) { if (t_check_trans()) { # NoLoose-Route, but stateful ACK. Must be ACK after 487
route(RELAY);
exit; } else { # ACKwithout matching transaction
exit; } } sl_send_reply("404","Not here"); } exit;}
I’m using TCP as the transport.
Kamailio: 4.2.3
Freeswitch: 1.5.15
I’ve attached a SIP trace from the point of view of Kamailio.
UAC: 10.0.0.40
Kamailio: 10.0.5.50
Freeswitch: 10.0.5.52
What is going on here?
The whole Record-Route thing confuses me a lot.

Grant
