This is a used Mitel I bought off the internet for our lab to test against our call recording application. Just powered it up today for the first time and am in the process of wiring up some Superset 4025s. All I really need is for a few digital extensions to come up.
I have 6 other PBXs I have bought in this manor and have always managed to get them working, but have never worked with Mitel. I received a parts list from another tech before I bought, but am embarrassed to say a SysID module was not on that list and I don't know if I have one. There is no MOSS sheet with the system, but I don't about options as long as I can make station to station calls on the 4025s.
