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,
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")) {/

=======================================================
As I read
on http://kamailio.org/docs/modules/4.3.x/modules/tm.html#tm.f.t_check_trans
<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.
