I suggest a disconnect timeout for call parked by an extension that is later placed in DND state. Note, if a call is placed in park orbit by an extension, and if that extension is placed in DND mode, the call will remain parked as long as the extension is in DND mode, there is no disconnecting act for the call. A time out for such is requested, or a refusal of DND when a call is parked by the extension.
Auto Attendant time out does not work for any time except 5 seconds. 10, 20 30 60 seconds do not work.
