Phone Screen Features
The phone screen shows information about your phone such as directory number, active call and line status,
softkeys, speed dials, and placed calls. The screen is made up of these sections:
Header sectiondisplays the phone number, Wi-Fi strength, battery charge, and a number of feature
icons. The feature icons display when features are active.
Middle sectiondisplays the home screen with its application (app) icons.
Footer sectiondisplays the current date and time or softkey labels. Each softkey label indicates the
action for the softkey button below the screen.
Differences Between Phone Calls and Lines
We use the terms lines and calls in very specific ways to explain how to use your phone. Here is an explanation
of the differences.
Lines
Each line corresponds to a directory number or intercom number that others can use to call you. Your
phone supports up to six lines. To see your phone lines, press Phone to open the line view. You
have as many lines as you have directory numbers with phone line icons in the line view list.
Calls
Each line can support multiple calls, typically up to four calls. Your phone can support up to 24 connected
calls, but your system administrator can adjust this number according to your needs. Only one call can
be active at any time; other calls are automatically placed on hold.
Here is an example: If you have two lines and each line supports four calls, then you could have up to eight
connected calls at one time. Only one of those calls is active and the other seven are held calls.
