Re: [SR-Users] [SIP Transaction] Handle Cancel message

Hi all, I have problem when use module pusher on Kazoo. The user after receive call from pusher can not receive the Cancel message if have another people pick up this phone. I trace log and debug on Kamailio and see the Freeswitch sent Cancel message but Kamailio reply 481 - Call leg/transaction does not exist. The configure on Kamailio: default.cfg ======================================================= /route[PREPARE_INITIAL_REQUESTS]/ /{/ / if (is_method("CANCEL")) {/ / if(t_lookup_cancel()) xlog("L_INFO","$ci|log|======== t_lookup_cancel()");/ / xlog("L_INFO","$rm from $fu (IP:$si:$sp) ---CAPTURED IN MAIN---\n");/ / if (t_check_trans()) {/ / xlog("L_INFO","$rm from $fu (IP:$si:$sp) ---CHECK TRANS TRUE---\n");/ / //xlog("L_INFO", "$ci|log|====================================");/ / route(RELAY);/ / } else {/ / xlog("L_INFO","$rm from $fu (IP:$si:$sp) ---CHECK TRANS FALSE---\n");/ / sl_send_reply("481", "Call leg/transaction does not exist");/ / }/ / exit();/ / } else if (is_method("ACK")) {/ / if (t_check_trans()) {/ / route(RELAY);/ / }/ / exit();/ / }/ ======================================================= As I read on http://kamailio.org/docs/modules/4.3.x/modules/tm.html#tm.f.t_check_trans Kamailio see the cancel message not same the transaction INVITE message.
