In this case, you use the trick from Andrew, like:

route{

      if (method=="REGISTER")
        {   
	    t_on_reply("3");
            if (!t_relay()) {
               sl_reply_error();
            }

               exit;
        }

}

onreply_route[3] {
	# Here we handle REGISTER replies
	xlog("L_INFO", "[$mi] [$rs $rr]\n");
	if (status=~"200") {
		route(3);
	};

route[3] {
	# workaround for location saving
	xlog("L_INFO", "saving location\n");
	save("location","r");
}


Your contacts will be saved by opensips only when a 200 OK was received 
for the REGISTER you send upstream.

Bogdan

> we are not challenging the UAC if the domain is not the opensips proxy, we just let it go through and save location. We take it if you issue a challenge here you need a copy of the credentials of the UAC on the opensips proxy, as we will not have this, is the above valid?
