Hi Denis,<br>
<br>
Yes, before the loose_route(), and it is critical as for sequential
requests, the matching against existing dialogs is done somewhere
inside loose_route() (via some callbacks). And when the dialog is
matched, the dialog timeout is updated, so this is why you need to
populate the AVP for dialog timeout before the loose_route.<br>
<br>
Dialog related variables will be available available after the
loose_route(), when the dialog was matched, so the dialog cotext is
available.<br>
<br>

Bogdan<br>

<p class="MsoNormal">Hi Denis,<br>
<br>
From a proxy point of view, a 200OK means the dialog was
establish. A proxy cannot interfere with the ACK part - the
acknowledgment is done between end parties.<br>
<br>
If the ACK is missing (in an established dialog), the callee
party (according to RFC) must send a BYE (when finishing the
200 OK retransmission) to the caller. This is something your
callee doesn't do.<br>
<br>
A simple work around is to use the dialog timeout in opensips:<br>
1) at INVITE time, when dialog is created, set a 5 seconds
timeout (dialog will be terminated by opensips, with BYE, in 5
secs after being established - do not forget to set the
BYE_ON_TIMEOUT flag)<br>
2) at ACK, before loose_route() set a new timeout to some
long, long (3 hours?) value.<br>
<br>
So, if the ACK will mis, the 5 sec timeout will kick in and
terminate the dialog; otherwise, opensips will prelong the
dialog on ACK time.<br>
<br>
Regards,<br>
Bogdan<br>
