Hi Klaus, > If Kamailio founds out that the topmost Router header is itself, then it will > remove it and use the nexxt Route header or the Request-URI.
Then, this case, the topmost Route: header is itself, then removes it (no more Route: headers) and finally must decides to route the request to the R-URI which is itself but at different port. However, it is not using that port (7080), but 5060. Why? In logs, after loose_route() is called, it writes: ERROR: <script>: WITHINDLG: method BYE with sip:321456@<sip-router_ip>:7080 _ DEBUG: siputils [checks.c:107]: totag found_ DEBUG: rr [loose.c:85]: is_preloaded: No_ DEBUG: <core> [socket_info.c:502]: grep_sock_info - checking if host==us: 13==13 && [<sip-router_ip>] == [<sip-router_ip>]_ DEBUG: <core> [socket_info.c:505]: grep_sock_info - checking if port 5060 matches port 7080_ DEBUG: <core> [forward.c:448]: check_self: host != me_ DEBUG: rr [loose.c:594]: Next hop: 'sip:<sip-router_ip>;lr=on' is loose router_ DEBUG: rr [loose.c:644]: The last route URI: 'sip:<sip-router_ip>;lr=on'_ ERROR: <script>: RELAY: method BYE with sip:<sip-router_ip>;lr=on _ ERROR: <script>: RELAY: calling t_relay() to sip:<sip-router_ip>;lr=on Message buffer: BYE sip:321456@<sip-router_ip>:7080 SIP/2.0__Via: SIP/2.0/UDP <remote_uac_ip>:5060;branch=z9hG4bKb111e6a26E0306F7__From: <sip:445566@<sip-router_ip>:5060>;tag=4DB62C24-2C3E0621__To: "321456" <sip:321456@<sip-router_ip>:7080>;tag=as369d9f82__Route: <sip:<sip-router_ip>;lr=on>__CSeq: 1 BYE__Call-ID: 15cbe04c69ede18c2e1f5a9221eea388@<sip-router_ip>:7080__Contact: <sip:445566@<remote_uac_ip>:5060>__User-Agent: UAc__Max-Forwards: 69__Content-Length: 0 loose.c finds it as "Next hop" and not as "Topmost route uri".
