I have an inherited Meridian 81c that evidentally someone took to disconnecting lines on the punch board, without removing them in software. I'm now just about out of available TNs and it's going to be time consuming to check all of the existing TN's that have nothing punched to them. Is it possible to list all of the disabled TNs so that I can check to see if they are phones on the floor that are unplugged, or if they are unproperly reclaimed phones?
