I am handling 302 response in the failure route and when receiving 302 response in kamailio, it's not going into the failure route , kamailio just executing the onreply route when 302 response are received.
A few days ago the same code with failure route worked but now it does not.
i dont know why kamailio is not executing a failure route from where we can redirect calls to another server.

code snippet 

route[RELAY]{
	t_on_reply("MANAGE_REPLY");
        t_on_failure("MANAGE_FAILURE");
	t_on_branch("MANAGE_BRANCH");

	if (!t_relay()) {
                sl_reply_error();
        }
        exit;
}
failure_route[MANAGE_FAILURE] {
        if (t_is_canceled()) {
                exit;
        }
	if (t_check_status("302")){
        	get_redirects("*");
       		$ru= $T_rpl($sel(contact.uri));
        	route(RELAY);
        }
}

kamailio version : 5.6.4
Please suggest if I am doing anything wrong.
