Display Phone Layout:

Your Cisco phone display functions are divided into four areas:

  • Touch screen: A touch screen is available on select Cisco IP Phone models. You can select or tap the touch-sensitive items with your fingertip, as opposed to using the phone buttons.
  • Soft keys: The soft keys, found at the bottom of the phone screen, are designed to guide users through call features and functions. Different soft keys will be displayed based on your phone’s status: when your phone is not in use, when you’re on a call, or if you have a caller on hold.
  • Line buttons: On your screen, you will see all of the extensions you have configured on your phone, which are indicated by the phone icon. To the right are the line buttons that allow you to place calls from any of those extensions. You can have anywhere between 1 and 8 line buttons depending on your model of IP phone.
  • Speed dial buttons: Any line buttons that are not configured with an extension can be utilized for speed dial buttons which will be indicated by a keypad icon.
