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!
=20
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.
