<div><tt>Hello Kevin,<br>
<br>
Once the B2B session started, the sequential request will not land to your script as they will be captured by B2B before the script (and handled according to the XML script).<br>
<br>
Still, with debug level 6 you should see various messages from OpenSIPS when the B2B would handle the re-INVITE.<br>
<br>
Are you sure the re-INVITE is actually reaching OpenSIPS on the right IP and port ?<br>
<br>
Regards,<br>

<div>I am trying to implement a simple topology hiding B2BUA with opensips 1.11.5<br>
<br>
most things work except that re invites for session expiry are being ignored.<br>
<br>
I assume that I am missing something in my config.<br>
<br>
the strange thing is that I see no debug to syslog when the Invites come in even with debug set to 9.<br>
<br>
the basic config is a client on port 5061 (C) inviting the B2BUA on port 5066(B) with then invites the main server on another host on port 5060(A).<br>
I do not expect and inbount calls from A<br>
<br>
C invites B, B invites A all proceeds normally until after 15 minutes A invites B and is ignored then sends bye a number of times.<br>
none of the reinvites or byes are reported in the logs.<br>
<br>
C then hangs up sending a bye to B, B sends a bye to A and gets 481 Unknown Dialog.<br>
<br>
below is my config<br>
<br>
route{<br>
if ( !mf_process_maxfwd_header("10") )<br>

sl_send_reply("483","To Many Hops");<br>
