I want !st say I apperciatate all you input and advise. I have installed the system and everything went well. I couldn't get the virtual Extension to work. I talked with NEC tech support and they said I was programed correctly (thanks to you guys). I was told I might have to upgrade the software because I'm 01.01 and the latest is 01.10.

Is this true? and all I have to do is copy it to any USB flash drive?
