[SR-Users] CANCEL is not processed in onsend_route

Hello all, I want to log the incoming and outgoing CANCEL on my Kamailio. I tried with a call of sip_trace in the default route setflag(22); if (method == "CANCEL") { sip_trace(); if (t_check_trans()) { t_relay(); exit; } } This works great, I get the incoming CANCEL in the Database. But the outgoing CANCEL is not logged with flag set. So I tried to use onsend_route with the following lines: onsend_route { xlog("L_NOTICE", " SENDING from $si \n $mb \n "); if ( method == "CANCEL" ) sip_trace(); } I am using Kamailio Version 3.1.0 (with Patch for Siptrace in onsend_route by Daniel ). But the CANCEL is not processed in the onsend_route at all. I do not even see the xlog-line. But tcpdump gives me the CANCEL outgoing. Following callflow: INVITE > 100 < < 100 < 180 180 < CANCEL> I am missing the last CANCEL. Why is the CANCEL not logged with flag 22 set? Why is the CANCEL not processed in the onsend_route? Greetings Timo
