This is what I was told by my vendor:

I was told by Toshiba application desk that WinAdmin was for the DK telephone systems. What you need is e-manager and the system would have to be upgraded to a minimum of version 3.0. You would need to give us a network connection and an internal static IP address and designate a PC where you want software installed. The software to upgrade the telephone system and the e-manager software is no charge.

Question, how do I find out what version system I have?
