I have recently taken over managing an NEC NEAX 2000 IVS.
There are 200 Extensions setup on this system but nowhere near as many handsets.
I have tried to setup a couple of new phones (IP Dterm) on unused extensions but they are coming up as “double assignment”.
I know how to fix the double assignment issue, but is there a way to report on IP phones that are currently active or extension numbers that are configured but do not have an active IP phone associated?
I would like to mark all spare extensions for future use.
