Firstly, I'm new to OpenSIPS so treat my comments accordingly.
But, can you do something in an onreply route?
eg, in a test setup I have, when I get an INVITE I do this:
create_dialog("pPB");
t_on_reply("doodle");
(I can't remember whether the dialog is needed for this)
and then I have this:
onreply_route[doodle] {
# expect $T_reply_code to likely first be 100
# then 180 or 183 for a progressing call
# 200 when call is answered
# or failure code (eg 4xx) or whatever
if (t_check_status("^1[0-9][0-9]$")) {
switch ($T_reply_code) {
case 180: $acc_extra(t_ringing) = $Ts; break;
case 183: $acc_extra(t_progress) = $Ts; break;
}
} else if (t_check_status("^2[0-9][0-9]$")) {
$acc_extra(t_answer) = $Ts;
} else {
xlog("Something else\n");
}
}
so when a 180 is received, it calls the above route function. Could you
send a CANCEL from there?
Cheers,
Kingsley.
