I'm trying to understand what the licensed phone numbers actually mean. For example in a 48 user system, do the Teleworker licenses mean you can only connect a total of 4 wireless phones (i.e. 48 + 4)?
The documentation seems to imply the 48 must be locally connected PoE phones only. So does that mean no more than 4 (wireless or remote PoE) phones can be registered with a UC500 system?
I understand the documentation can be confusing and I guess only some cisco marketing person could tell you why it's done so.
What I can tell you with certainty is that any CME system, UC520 included, does not enforce any limitation to user topology beside the maximum number of registered phones.
