Hello,

the pcap files don't show much when I open them, maybe the email servers/clients corrupted the enconding, as I faced similar issues in the past -- can you make a tgz archive and resend them?

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

Thank for your support !

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.

Hi all,

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]

            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");
