I am working on a Definity/early CM R013i.01.2.632.1 in a hotel. The manager wants to block guest room to guest room calling without going through the attendant. I don't know what PMS they are using, but controlled restriction appears to change User Cntrl Restr: from none to toll, although I don't believe that has anything to do with room to room calling anyway. Can guest room to guest room calling be restricted/blocked?
