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.
- 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]/ /{/ / 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. Kamailio doesn't send 481 from the C code in the case of call, it either receives it or it is something in config.
