I'm trying to arm the failure route for a message sent via uac_req_send - similar to:
{ $uac_req(method)="OPTIONS"; $uac_req(ruri)="sip:kamailio.org"; $uac_req(furi)="sip:kamailio.org"; $uac_req(turi)="sip:kamailio.org";
t_on_failure("UAC_FAIL"); uac_req_send(); }
failure_route("UAC_FAIL") { xlog ...... }
If there is no response from the remote server, kamailio resends until the timers expire; but the failure route is not run. Similarly, if a 404 is sent back from the remote server, the failure route is not run.
Am I missing something obvious?
Thanks
