Telephone Feature Overview
Reading the Display
Looking at your phone your extension appears at the center of the display. The
current date and time will be shown across the top of the display. The four
context-sensitive buttons will change depending on what the phone is doing. For
example, when the phone is sitting idle it will show (from left to right) History,
Directory, DND (Do not Disturb), and Menu. History will show a list of all calls.
Directory will provide you with a list of saved contacts. DND will turn on Do Not
Disturb mode, which will prevent your phone from ringing. The Menu button will
bring up options to make changes to the settings of your phone.
