Re: [SR-Users] BYE not forwarded

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. T 10.0.5.52:54822 -> 10.0.5.50:5060 [AP] BYE sip:grant@10.0.0.40:5060;transport=tcp SIP/2.0. Via: SIP/2.0/TCP 10.0.5.52;rport;branch=z9hG4bK99X8a4Q8BFy1a. Route: <sip:10.0.5.50;transport=tcp;lr=on>.

Must be ACK after 487 route(RELAY); exit; } else { # ACK without 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.
