It is possible to activate or deactivate the DND mode on a per-line basis. If DND mode is activated for a specific line, all incoming calls to the line will be rejected automatically, and the callers will hear a busy tone.

To activate DND mode for a specific line via the handset:

    1. Press OK to enter the main menu.
    2. Select Call Features > Do Not Disturb. The screen will display the incoming lines currently assigned to the handset.
    3. Press Up or Down key to highlight the desired line, and then press the OK soft key.
    4. Press Right or Left key to select Enabled from the Status field.
    5. Press the OK soft key to accept the change.

    The Stop icon on the status line indicates the DND mode is activated. You can press the Line soft key
    when the handset is idle to check the line status. The Stop icon in the bottom of a line indicates that the DND mode is activated for this line. The handset will reject all incoming calls to this line, and the LCD screen displays the missed call icon followed by the number of missed calls.
