I did the following

drop;

But there is an issue.
When 180 is followed by 200 instantly, the CANCEL is not working as expected.
When I add a delay on Answer ie 1sec then CANCEL works.
Any suggestion?

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.

Dear all
I am trying to create a service which will generate missed calls. In
order to be more accurate, I want to CANCEL the request when 180 is
received.
The scenario is the following
Asterisk Invite -> OpenSIPs -> Carrier
Carrier 183 -> OpenSIPs -> Asterisk
Carrier 180 -> OpenSIPs
OpenSIPs Cancel -> Carrier
Is that possible to be done from script without external app?
Regards
