Clean the Phone Screen
Procedure
If your phone screen gets dirty, wipe it with a soft, dry cloth.
Do not use any liquids or powders on the phone because they can contaminate the phone components
and cause failures.
Caution
Badged Icons
If you have missed calls, the missed call icon, and a counter showing the number of missed calls, display on
your phone desktop. If you receive a voicemail, the missed call icon changes to the voicemail icon and
voicemail counter until you listen to your messages.
In addition, if you have more than one call on a line, either the held icon or the off hook icon change to show
the number of calls.
Differences Between Phone Calls and Lines
We use the terms lines and calls in very specific ways to explain how to use your phone.
Lines—Each line corresponds to a directory number or intercom number that others can use to call you.
You have as many lines as you have directory numbers and phone line icons. Depending upon how your
phone is configured, you could have up to 16 lines.
Calls—Each line can support multiple calls. By default, your phone supports four connected calls per
line, but your 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.
