[SR-Users] UAC Register Asterisk

[Alberto Sagredo]

Hi

Im trying to modify example for Asterisk/Kamailio integration that miconda
did, and trying to handle Forwarded register to Asterisk in an
authenticated way instead removing secret in asterisk.

I have made this changes


route[REGFWD] {

        if(!is_method("REGISTER"))

        {

                return;

        }



        $var(rip) = $var(astip);

        $uac_req(method)="REGISTER";

        $uac_req(ruri)="sip:" + $var(rip) + ":" + $var(astport);

        $uac_req(furi)="sip:" + $(au{s.substr,8,0}) + "@" + $var(rip);

        $uac_req(turi)="sip:" + $(au{s.substr,8,0}) + "@" + $var(rip);

        $uac_req(hdrs)="Contact: <sip:" + $au + "@"

                                + $sel(cfg_get.kamailio.bindip)

                                + ":" + $sel(cfg_get.kamailio.bindport) +
">\r\n";

        if($sel(contact.expires) != $null)

                $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " +
$sel(contact.expires) + "\r\n";

        else

                $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " +
$hdr(Expires) + "\r\n";


        xlog("Dentro de REGFWD");


        t_on_failure("REG_AST");


        uac_req_send();


}




 failure_route[REG_AST] {


    if (t_is_canceled()) {

        exit;

    }


    xlog("Dentro de REG AST");


    if(t_check_status("401|407")) {

        xlog("Dentro de 401");

        $avp(auser) = "test";

        $avp(apass) = "test";

        uac_auth();

        t_relay();

        exit;

    }

}


What i see  on traces:

But Kamailio is not sending authentication .

Any idea what could be wrong? Or any tip to do what i try.

The idea is that a sip endpoint register with authentication on kamailio
and it sends register with authentication to asterisk.

Thanks in advance
