I need some clarification. I would be happy to RTFM, but I can't find any documentation in TFM to clarify my question. I want to add another SCN to a system that will put my total users over the 500 limit. When counting the total users, is it just the total of the users in the manager program of each system? Do analogue users make a difference in the total? Does a virtual user (no extension) count against the total? Does the user count against the total if there is not an acutal digital or analogue phone plugged into the system (we have some spares set up so we can easily add them remotely). If I just set up an IP line to the hub and set the dial plan and force it over the IP line and leave the voice networking off, does that count against the total? I know that upgrading to R6 will solve my issue, but I can't do that yet. There is a need of some other hardware upgrades first. Nothing can ever be simple. Any help or direction in TFM would be greatly appreciated.
