Hey all;

    I am trying to remote registration between Kamailio and Asterisk. I tried remote Registration with UAC module. But this module doesn't work online. So that i wrote my remote registration code, is below. But there is a little problem that i cant take Authentication header to onfailure_route so that cannot forward Auth to client.  it is working well with uac_auth but gets this error (" run_failure_handlers(): ERROR: run_failure_handlers: Error in run_top_route ") so cannot trust this function.
How can i get Auth header to add

    Thanks for helps.

My Code:

route[REMOTEREG]{

        xlog("L_INFO","Remote Reg: $fd : $rm : $fU : $si : ");

        sql_xquery("ca","CALL kamailio.route_3xx( '$fd', '$rm');  ","ra");

        xlog("L_INFO","Remote Reg:ip_addr:$xavp(ra=>ip_addr): \n");

        if($xavp(ra=>ip_addr)!=$null){

                                        $avp(ipmiz)=$xavp(ra=>ip_addr);
                                        xlog("L_INFO","pump it:$rU:$avp(ipmiz):$ru:$rd");
                                        $ru="sip:"+$fU+"@"+$avp(ipmiz);
                                        xlog("L_INFO","pump it :new::$avp(ipmiz)");
                                        t_on_failure("REMOTE_AUTH");
                                        t_on_reply("REGISTER_SUC");
                                        if(!t_relay()){
                                                t_reply("408", "have a problem");
                                                exit;
                                        }
                                        exit;
        }

        return;
}

failure_route[REMOTE_AUTH]{
                xlog("L_INFO","REMOTE_AUTH:$fU:$si$rm:$ci:$adu:ar:$ar");
         if ($T_reply_code == 401 or $T_reply_code == 407) {
                xlog("L_NOTICE", "Remote asked for authentication ");
                #uac_auth();
## need to add Authentication header.
                append_to_reply("Allow:$hdr(Allow) \r\n");
                t_reply("$T_reply_code","Unauthorized");
        }
}

onreply_route[REGISTER_SUC]{

        xlog("L_INFO","REGISTER_SUC");
        if(t_check_status("200")){
         if (!save("location"))
         {
                xlog("L_NOTICE", "Register yapilamadi");
         }
               exit;
        }


}
