Thanks for the quick response Alex!

As an alternative, this seems to work, although seems hackish; better 
suggestions welcomed.

route {
   ...
   if (( $ru == "sip:deadbeef at 127.0.0.1" ) && ($ri == "127.0.01") ) {
       $ru = "sip:kamailio.org";
       t_on_failure("UAC_FAIL");
       t_relay();
       exit;
    }
   ...


    $uac_req(ruri)="sip:deadbeef at 127.0.0.1";
    ...
    uac_req_send();
}
