[Users] * sip response 407 when using dispatcher (Help Please)

Hi All,

    I am trying to set up SER with Dispatcher to loadbalancing the traffic
to 2 * boxes. SER was able to select the * IPs from the dispatcher.list, but
* SIP response back authentication required. It work perfectly if I i use
rewritehostport instead of using the dispatch module. I am pulling my hair
now and still don't know where the problem at.

openser.cfg
        if (uri=~"sip:\+?[1-9][0-9]*@.*") {
                ds_select_dst("2", "0");
                route(4);
                route(5);
                return;
        };

route[4] {


        if (isflagset(6)) {
                force_rport();
                fix_nated_contact();
                force_rtp_proxy();
        };
}

route[5] {

        setflag(1);
        t_on_reply("1");
        forward(uri:host, uri:port);
        append_hf("P-hint: main PSTN route\r\n");
        t_on_failure("1");
        if (!t_relay()) {
                sl_reply_error();
                return;
        };
}

onreply_route[1] {

        if (isflagset(6) && status=~"(180)|(183)|2[0-9][0-9]") {
                if (!search("^Content-Length:[ ]*0")) {
                        force_rtp_proxy();
                };
        };

        if (nat_uac_test("1")) {
                fix_nated_contact();
        };
}

failure_route[1] {

       append_hf("P-hint: backup PSTN route\r\n");
       rewritehost("x.x.x.x");
       rewriteport(   "5060");
       append_branch();
        t_relay();
}
