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.
