Hi Denis,
I can tell it works for sure, as I'm using this kind of dirty trick to
cope with some buggy clients.
Best regards,
Bogdan

Hi Denis,
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.
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.
A simple work around is to use the dialog timeout in opensips:
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)
2) at ACK, before loose_route() set a new timeout to some long,
long (3 hours?) value.
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.
Regards,
Bogdan

Hello!
I noticed that cdr_flag in acc modules marks dialog for accounting as
answered even there was no ACK on 200 OK.
As a result, I have acc record which has a big duration and status 200 OK.
Thank you for any help.
