Hi Daniel, I send you 2 files pcap, capture on server side. + Server: 192.168.1.77 + Client: 192.168.1.134 + Scenario: User 102 call to ring group 777 - has user 100 (192.168.1.134) and user 101 (192.168.1.164). User 100 is offline but it's configured push notification from Apple to wake up, register and receive INVITE. I pick up phone on 101 but 100 can not receive the CANCEL message to stop the ringing tone. 1) Pusher_ok.pcap: User 100 can revice the CANCEL message. 2) Pusher_failed.pcap: As I told above, when user 101 pick up the phone, Freeswitch send CANCEL message to user 100. But when message go to Kamailio, Kamailio reply 481 - Call leg/transaction does not exist. (I can't capture this packets). I also include the log on Freeswitch send CANCEL message and revice the 481. Kamailio doesn't send 481 from the C code in the case of call, it either receives it or it is something in config. => This is configure on kamailio: default.cfg, it check *t_check_trans()* ======================================================= *route[PREPARE_INITIAL_REQUESTS]* *{* * if (is_method("CANCEL")) {* * if (t_check_trans()) {* * route(RELAY);* * } else {* * sl_send_reply("481", "Call leg/transaction does not exist");* * }* * exit();* ======================================================= Thank for your support !
