      <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="set"
        data="bind_server_ip=my.server.ip"/&gt;<br>
        &lt;X-PRE-PROCESS cmd="set"
        data="external_sip_ip=my.server.ip"/&gt;<br>
        &lt;X-PRE-PROCESS cmd="set"
        data="external_rtp_ip=my.server.ip"/&gt;<br>
        internal.xml<br>
        &lt;param name="ext-rtp-ip" value="$${external_rtp_ip}"/&gt;<br>
        external.xml<br>
        &lt;param name="ext-sip-ip" value="$${external_sip_ip}"/&gt;<br>
        &lt;param name="ext-rtp-ip" value="$${external_rtp_ip}"/&gt;<br>
