I see an Idle Timer plugin is now available for FOP2. The description states "Displays an idle timer on extensions, to know how long since they last received a call." Is this counter the same value we would see on the Realtime tab of Call Center Stats labeled there as "Last In Call"? So idle is relative only to inbound queue calls. I don't believe Asterisk actually tracks an actual idle time for a user so I expect this is the case. Although I would be very happy if this is something more.
