Hello all. I have a G3R V7 and a G3si V7. I've been tasked to find out how many assigned extensions we have that are not being used (our subscribers love to leave and not tell us). I have been going through my displayed alarm list and testing all the analog stations that I find there. Which ever ones give me a 48 fail code, I treat as not having terminating equipment (a physical phone) connected. These extensions I remove. Is there another way to determine the frequency which a particular extension is used? Can the software tell me that ext 4567 was last used on 12-09-01?
