[OpenSIPS-Users] Generate CANCEL on 180

[Antonis Psaras]

I did the following

if (t_check_status("180"))
{
	t_cancel_branch();
               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.
