Hello again,
Please see the attached wireshark trace, I tried for a sipgrep trace but
couldn't somehow. I hope this will get me some clue on what I'm doing wrong.
This is a setup with Kamailio in front of Asterisk Servers. Kamailio is
multihomed and MS are on private IPs, all the calls are routed to MSs and
then comeback for further dial-outs.
Please see the Continuous CANCEL requests which aren't terminating the call.
Thanks,
Sammy.

Hello,
send the ngrep trace of such call, from the initial INVITE, you can use:
ngrep -d any -qt -W byline port 5060
The sip trace will help to see what is wrong with that CANCEL.
Cheers,
Daniel

Hello list,
I'm using Kamailio 3.1.5 in front of asterisk servers. Kamailio
handles all the SIP registrations. Calls from SIP phones are forwarded to
asterisks and then dialled out to Kamailio.

Problem:
When call is initiated from a softphone and is in ringing phase, CANCEL
just don't work. I've done some initial debugging and the following piece
of code in main route is failing.
# CANCEL processing
if (is_method("CANCEL"))
{
xlog("L_NOTICE","$rm from $fu (IP:$si:$sp) ---CAPTURED IN
MAIN---\n");
if (t_check_trans()){
t_relay();
xlog("L_NOTICE","$rm from $fu (IP:$si:$sp) ---CHECK TRANS
TRUE---\n");
}
xlog("L_NOTICE","$rm from $fu (IP:$si:$sp) ---CHECK TRANS
FALSE---\n");
exit;
}
Also the CANCEL fails the has_totag() condition !
The same Call CANCEL scenario works fine for any client on Public IP !
Hope to get some pointers for the solution.
Regards,
Sammy.
