How to use Do Not Disturb
Enabling Do Not Disturb (DND) sends all incoming calls directly to voicemail. Your caller hears the phone ringing, but you do not. All calls you receive while DND is enabled are logged to your Recent Calls list.
1. From the Home screen, touch the DND icon.
2. If your phone is idle, the DND icon appears next to your phone line in the lines view.
If you have new messages, the Messages icon appears instead.
