    <tt>Hi Schneur,<br>
      <br>
      A failing ACK may indicate the problem with sequential routing
      -&gt; in the route set opensips puts the real/advertise IP....basically
      an IP.<br>
      <br>
      While in domain table you usually put FQDN / domains. Of course,
      you could put the advertised IP in the domain table. It will do
      the trick but it will be a kind of misusage (you use a tool for
      SIP routing to fix some IP routing issue).<br>
      <br>
      This is why I recommend to use the alias global param in
      combination with the advertised address.<br>
      <br>
      Regards,<br>
    </tt>

                <br>
                Actually there is simpler solution, if you want to keep
                your listener with the IP. Just add:<br>
                    alias="<a moz-do-not-send="true"
                  href="http://yourdomain.com" target="_blank">yourdomain.com</a>"<br>
                <br>
                So, even OpenSIPS is listening on IP x.y.z.w, it will
                know it is responsible for handling traffic for the <a
                  moz-do-not-send="true" href="http://yourdomain.com"
                  target="_blank">yourdomain.com</a> SIP domain.<br>
