    <font face="Arial">Hi,<br>
      <br>
      I could make a call within NAT without any problem.<br>
      When I made a call from internet, I got no audio.<br>
      I have read the document <br>

    <font face="Arial"><font face="Arial">and set the parameters.<br>
        vars.xml<br>
        &lt;X-PRE-PROCESS cmd=&quot;set&quot;
        data=&quot;bind_server_ip=my.server.ip&quot;/&gt;<br>
