Oh so you're referring to an options card in the VM not in the DHS? The way you phrased your previous post I thought it was in the main phone system.

Unfortunately we had to hire out to the local tech support shop because the boss needed the phones back yesterday. If they tell us the system is ending its lifecycle we'll have to get something else, but I'm personally hoping it's something fixable or replaceable, money for a new phone system might not be in the pipe.
