What does the Contact header in the INVITE look like?<br><br>The BYE is actually a separate SIP dialog, and the SIP server has to send it to the address in the Contact header not the address the INVITE came from.<br><br>NAT or a misbehaving SIP client could potentially screw that up by sending a bad Contact header, which might mean you're not seeing it in Wireshark because it's not being sent where you expect.<br>

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">It should happen automatically. Is A behind NAT? Sounds like a firewall/NAT may be dropping the bye. Also, have you done a debug on FS to see if it actually sends a bye or not to A?<u></u><u></u></span></p>
