DND feature enables the phone to reject all incoming calls automatically when you do not want to be interrupted.
You can choose to implement DND locally on the phone or on the server-side.

Usually, you can activate DND when the phone is idle. The phone stays in the DND state until you deactivate DND manually.

You can also temporarily activate DND during calls, the new incoming calls are rejected automatically. After ending the call, the DND is deactivated automatically. It prevents from interrupting during current calls and avoids missing calls after calls end.

The following table lists the parameters you can use to configure the DND settings.
