The Do Not Disturb feature allows you to silence your handset and manage incoming calls automatically. When DND is active:
Incoming calls are rejected and redirected to voicemail or your "Busy" destination.
If you have Call Forwarding (Unreachable) configured, the call will follow those specific routing rules.
How to Activate DND
Ensure the phone is idle (not in an active call).
Press the DND soft key located at the bottom of the LCD screen.
Verify Activation: Look for the DND icon (typically a red "minus" or "no entry" sign) in the top-right corner of the status bar.
Note: While DND is active, you will still see a notification for "Missed Calls" on your screen so you can keep track of who reached out.
How to Deactivate DND
Press the DND soft key again.
Verify Deactivation: The DND icon will disappear from the top of the screen.
Test: Your phone is now ready to receive calls normally.
