Avaya^TM 6400 Series Digital

The Avaya^TM 6400 Series Digital Voice Telephones deliver the right combination of business communication functionality. For example, you can personalize your phone by programming the buttons on your telephone simply by choosing from a selection of convenient features.

Your business will benefit from these productivity-building features:

6402 Display	6408 Display	6416 M Display	6425 D + M Display

Whisper Page lets you know when a call is waiting without intruding on a call in progress, so you never miss an important call.

Group Listening lets you take a call using your handset while others only listen over your speaker, so the group can hear a critical conversation.

Group Paging let's you use the speaker built into your telephone to page all non-active phones within a specific workgroup or area, for quick response to calls.

Automatic Call Timer lets you set your telephone to start timing a call as soon as the call connects (requires Avaya^TM Call Processing Release 6.3 or higher and a 6400 display telephone) so you can track time spent.

One-touch operation with headsets frees your hands by letting you conveniently answer, hang up, and dial without having to pick up the handset. You can also use specialty handsets, shoulder rests, and long cords for maximum comfort and mobility.

There are a variety of 6400 Series models that can meet your specific requirements and deliver exceptional benefits to your business:
