      analogue extensions. You can speak to callers at
      the door and release the door lock, all at the
      push of a button.

      Music on Hold:
      The built in AIS Module can be uploaded with
      your choice of music, information– or advertising

      System Phones:

      Trunk Line, can support besides ISDN Devices
      and Analogue Extensions up to two AGFEO ISDN
