      <br>
      thank you for your fast response.<br>
      It is not a FreeSwitch problem!<br>
      <br>
      I solved it in the meanwhile.<br>
      It was a firewall rule problem.<br>
      FreeSwitch was not able to reach the proxy server.<br>
      Strange fault, since I was able to make calls.<br>
      <br>
      Problem is solved.<br>
      <br>
      Thank you!<br>

          <br>
          we need a proxy (kamailio) in front of freeswitch.<br>
          In general it works, but ...<br>
          I get no BYE if the client direct connected to freeswitch
          hangs up.<br>
          <br>
          The INVITE from the proxy contains the correct Record-Route
          entry:<br>
          <br>
          INVITE <a class="moz-txt-link-freetext" href="sip:yyy@xxx.xxx.xx;transport=TCP">sip:yyy@xxx.xxx.xx;transport=TCP</a> SIP/2.0<br>
          Record-Route:
          <a class="moz-txt-link-rfc2396E" href="sip:proxy.address.xxx.xxx;transport=tcp;lr"><sip:proxy.address.xxx.xxx;transport=tcp;lr></a><br>
