    <p>Hello,</p>
    <p>REGISTER requests are typically only with the address of the
      server in request URI, no username there. So this if fine to have
      $rU being NULL.</p>
    <p>No relaying means that From header and To header have URIs with
      domains not belonging to local SIP server. Check alias and listen
      parameters.<br>

    Cheers,<br>

        <div>Hello all,</div>
        <div>     I have two kamailio servers(A and B) with exact same
          config using the same mysql db. I can register to A but not B.
          Server B complained:</div>

        <div><b>     </b>After capture the udp packet on both server

        <div><b>     </b></div>
        <div>     I don't have a clue what went wrong.  How come the $rU
