[OpenSIPS-Users] Generate CANCEL on 180

[Kingsley Tart]

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.
