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.
