Buttons and Hardware

Your phone provides quick access to your phone lines, features, and call sessions:
• Programmable feature buttons (left side): Use to view calls on a line or access features such as Speed
Dial or All Calls. These buttons are also called feature buttons.
• Session buttons (right side): Use to perform tasks such as answering a call, resuming a held call, or
(when not being used for an active call) initiating phone functions such as displaying missed calls. Each
call on your phone is associated with a session button.
