I understand, thank you From: Bogdan-Andrei Iancu [mailto:bog...@opensips.org] Sent: Tuesday, May 10, 2011 12:56 PM To: Denis Putyato Cc: 'OpenSIPS users mailling list' Subject: Re: [OpenSIPS-Users] dialog and acc Hi Denis, 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. Dialog related variables will be available available after the loose_route(), when the dialog was matched, so the dialog cotext is available.

I want to use $dlg_status variables to check if dialog exists (When received ACK), but in documentation said that this variables works only after loose_route() function From: Bogdan-Andrei Iancu [mailto:bog...@opensips.org] Sent: Tuesday, May 10, 2011 12:43 PM To: Denis Putyato Cc: 'OpenSIPS users mailling list' Subject: Re: [OpenSIPS-Users] dialog and acc Hi Denis, I can tell it works for sure, as I'm using this kind of dirty trick to cope with some buggy clients.

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.

As a result, I have acc record which has a big duration and status 200 OK.
