You can use the Do not disturb feature to avoid audio notifications for all direct incoming calls. The phone redirects these incoming calls to a predefined coverage number that your system administrator sets. The feature is also referred to as Send all calls. If required, contact your administrator to name this feature on your phone as Send all calls.
When the Do not disturb feature is active, you can still receive the incoming calls from the following active features:
Automatic Callback
Priority Call
Call forward
