Add Line Appearance Keys

With 8x8 Line Appearance Keys (LAK), you can handle multiple concurrent calls. 8x8 phones have LAKs that handle calls for the user’s extension. By default, a user’s phone will have two LAKs to make it easier for a user to switch between two calls using the buttons on the phone. You can add up to four LAKs on the main phone device. This is the number of calls you can have active at any given time. You can add or remove the Line Appearance Keys from the 8x8 Admin Console and push them to the phone device.


  • Receive and handle multiple live calls at the same time.
  • Support one to four default LAKs The number of LAKs depends on your phone. For example, Cisco devices support one LAK but four concurrent calls.


Cisco phones show one key on the left and four lines on the right when the key on the left is selected. Keys cannot be added or removed on Cisco phones.
