That should just work (tm).

What is the config for you redirector?

Essentially it is the "default" kamailio config with a 
send_reply("302", "Redirect");

request_route {

        # per request initial checks
        route(REQINIT);

        force_rport();

        # CANCEL processing
        if (is_method("CANCEL"))
        {
                if (t_check_trans()) {
                        route(RELAY);
                }
                exit;
        }

        # handle requests within SIP dialogs
        route(WITHINDLG);

        ### only initial requests (no To tag)

        t_check_trans();

        $rd="somewhere.else";

        send_reply("302", "Redirect");
        exit;
}
