Re: stir/shaken integration with clearip redirect method

Hey JR,

Basic aspects of what I do…

Change the ru like you already have and then add something like:

if (!t_is_set("failure_route")) t_on_failure("MANAGE_FAILURE_STIR”);

Then 2 aspects…

onreply_route[MANAGE_REPLY] {
	if (t_check_status("30[1-2]")) {
		if (is_present_hf("Identity")) {
			$avp(stir) = $hdr(Identity);
			xinfo("Identity found: $avp(stir)\n");
		}
	}
}



failure_route[MANAGE_FAILURE_STIR] {
	xinfo("$T_reply_code received.\n");
	if (t_is_canceled()) {
		exit;
	}

	if (t_check_status("30[1-2]")) {
		if ($avp(stir)!=$null) {
			if (!is_present_hf("Date")) {
				append_time_to_request();
				xinfo("Date header added\n");
			}

			append_hf("Identity: $avp(stir)\r\n", "Server");
			xinfo("Identity header added: $avp(stir)\n");
		} else {
			xinfo("Identity not detected\n");
		}

		route(WHEREVER);
	}

	t_reply("404","Cannot Send MFS1");
}

I've got the basic connection to clearip using t_relay_to_tcp for testing, but I'm struggling with the checks and timeouts. I have call progress past the initial request where I need to wait for a response. Should I put the clearip invite in its own route block use return? Has anyone successfully integrated the redirect method with kamailio to clearip and can give me some example route checks in the kamailio configs?
