The details

• Full integration
  With an ESI C-Plus business communications system, just one compact cabinet does what other systems must combine multiple boxes to do. This makes installation and maintenance much simpler.
   
• Grows with your business or organization, with up to:
  • Eight lines × 16 digital stations × four fully functional analog ports.
  • Four built-in voice mail ports.
  • Six-hour voice storage.
     
• Digital Feature Phones
  • Two versions: 24-Key and 12-Key.
  • Fully digital 2B+D.
  • Stylish and compact, to fit any workspace.
  • Convenient four-position tilt mount; also wall-mountable.
  • Simple installation with one-pair, non-polarity-sensitive wiring.
  • “Ruggedized” design resists abuse and spills.
  • Big, easy-to-read display (24-Key Feature Phone available with backlit display). Provides various combinations of the following, depending upon the system configuration, the ESI Feature Phone model and the current operation:
    — Date and time
    — Current line usage
    — Phone number dialed
    — Name of caller1
    — Elapsed time on current call
    — Remaining time on currently playing message or recorded call
  • Dedicated feature keys; Esi-Dex™ (indexed speed-dialing) keys; and up/down keys for independent digital control of speaker and handset volume.
  • Programmable feature keys provide one-touch access to stations, lines, speed-dialing and other features.
  • Tri-color LEDs make keys’ use even easier.
