  • Feature and Line Buttons

    • Feature buttons—Used for features such as Speed dial or Call pickup, and to view your status on another line.

    • Line buttons—Used to initiate or answer a call or resume a held call. You can also use a line key to open and close the call session window and to navigate through the call session window. Open the call session window to see the calls on the line.

  • Feature and line buttons illuminate to indicate status:

    • Green—Line is idle.

    • Red Steady—Line is active or in use.

    • Red Flashing—Line is on hold or there is an inbound call.

    • Amber Steady—Line is unregistered (cannot be used).
