Feature Request: in acc allow setting variables for *_extra_bye after loose_route

[rrb3942]

Currently if you use the *_extra_bye options in the Acc module you must make sure that the variables are set before calling loose_route or they are not populated.

This can be problematic if you need to access data associated with the dialog (such as a $dlg_val) for calculations or other processing to populate those values. Making it so that they can be populated after calling loose_route (such as the change made to $DLG_timeout in 1.11) would make this much easier and more intuitive.

Hello,

This can be achieved now by using the dialog exported events ( see http://www.opensips.org/html/docs/modules/2.1.x/dialog.html#id297207 )
By using the event_route module ( http://www.opensips.org/html/docs/modules/2.1.x/event_route#id293506 ) and declaring a script route as route[E_DLG_STATE_CHANGED] , you will be able to detect when the dialog switches from the 4 state ( established ) to state 5 ( ended ) - the route will get called before the accounting is done, thus allowing you to populate your variables.

Best Regards,
Vlad

Hey Vlad,

Thank you for the response. That will work great for me.

I still think that it is a bit unintuitive that any variables after calling loose_route don't get accounted for, as loose_route tends to be one of the very first calls that will be made on a request with a totag (which a BYE is pretty much guaranteed to have).

The documentation should at least mention this, as I know it was not obvious to me when I first attempted to use it.

Thanks for your help.

Pretty sure this is all taken care of with the new accounting variables and changes.
