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 !
Regards,
Hai Bui
