[kamailio/kamailio] outbound + loose_route: new exit code when flow token does not exist (Issue #4315)
by sergey-safarov 24 Jul '25

24 Jul '25

sergey-safarov created an issue (kamailio/kamailio#4315) ### Description Use case WebRTC client connected to Kaamilio Edge proxy. For network connectivity reasons, the flow token may no longer be valid. In this case, behavior should be described in the [RFC5626, 5.3.1 Processing Incoming Requests](https://datatracker.ietf.org/doc/html/rfc5626#section-5.3.1) > If the flow no longer exists, the proxy SHOULD send a 430 (Flow Failed) response to the request. Also [9.3 Incoming Call and Proxy Crash](https://datatracker.ietf.org/doc/html/rfc5626#section-9.3) > Bob's authoritative proxy first tries the flow to EP1, but EP1 no longer has a flow to Bob, so it responds with a 430 (Flow Failed) response. To get it working, it will be fine to use construction like ``` if (!loose_route()) { switch($rc) { case -4: sl_send_reply("403", "Flow Failed"); exit; case -2: sl_send_reply("403", "Forbidden"); exit; default: xlog("L_ERR", "in request_route\n"); sl_reply_error(); exit; } } ``` Where `loose_route` returns a new error code (`-4` for example). This error code is generated when the flow token points to not existing TCP/TLS/WSS connection. ### Expected behavior Kamailio `loose_route` allows the check of flow token validity before messages related via non-existent TCP/TLS/WSS connections. #### Actual observed behavior For now, Kamailio tries to relay messages to non-existent client connections and generate an error message like ``` 477 Unfortunately error on sending to next hop occurred (477/TM) 500 Message processing error (2/TM) ``` #### How to reproduce Required to start Kamailio with a config like ``` listen=udp:127.0.0.1:5060 listen=tcp:127.0.0.1:5060 loadmodule "pv.so" loadmodule "xlog.so" loadmodule "sl.so" loadmodule "tm.so" loadmodule "siputils.so" loadmodule "rr.so" loadmodule "stun.so" loadmodule "outbound.so" modparam("outbound", "force_outbound_flag", 1) modparam("outbound", "flow_token_secret", "kamailio") loadmodule "debugger.so" modparam("debugger", "cfgtrace", 1) modparam("debugger", "log_level_name", "exec") request_route { loose_route(); switch($rc) { case -3: xlog("L_ERR", "loose_route code -3\n"); break; case -2: xlog("L_ERR", "loose_route code -2\n"); break; case -1: xlog("L_ERR", "loose_route code -1\n"); break; case 1: xlog("L_ERR", "loose_route code 1\n"); break; case 2: xlog("L_ERR", "loose_route code 2\n"); break; } record_route(); if (has_totag()) { t_relay(); } else { t_relay_to_udp("127.0.0.1", "5080"); } } ``` Then need to start SIPp server script using the command ``` sipp -sf uas.xml -p 5080 -d 4000 -bind_local 127.0.0.1 ``` And then start SIPp client script using the command ``` sipp -sf uac.xml -m 1 -t t1 127.0.0.1 ``` Where `uac.xml` and `uas.xml` are attached [sipp-scripts.tar.gz](https://github.com/user-attachments/files/21187724/sip… -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4315 You are receiving this because you are subscribed to this thread.
