your Asterisk server at all. Try doing a packet trace on the network<br>
segment where the calling SIP agent is and see where it&#39;s trying to<br>
send the ACK to. My guess would be your firewall is incorrectly<br>
handling the SIP messages. Generally it&#39;s very bad news to use an ALG<br>
or firewall to mangle SIP packets as they almost always get it wrong.<br>
<br>
In your case there is a Record-Route header in the response so the ACK<br>
request should be being sent to that address. Perhaps your firewall is<br>
not correctly mangling that to allow the request to find its way back<br>
to your Asterisk server.<br>
