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.

Hello,
can you provide pcap (or full ngrep output) for all messages of such a call, from initial invite, including all responses and the other requests? The sip trace has to be taken on kamailio server.
Kamailio doesn't send 481 from the C code in the case of call, it either receives it or it is something in config.
Cheers, Daniel

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();* =======================================================

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.
- Pusher_ok.pcap: User 100 can revice the CANCEL message.
- 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]* *{*

Hello,
can you provide pcap (or full ngrep output) for all messages of such a call, from initial invite, including all responses and the other requests? The sip trace has to be taken on kamailio server.
