When you enable 'do not disturb’:

• Calls to you are redirected to voicemail if available. Otherwise, the callers hear busy tone.

• People calling from numbers in your 'do not disturb' exceptions list can still call you and forwarding can still be applied to these calls.

• Calls to any hunt group of which you are a member are no longer presented to you (unless you are the last available member of the group).

• Call already alerting your phone are not affected and continue alerting.

• You can still use the phone to make outgoing calls. When you go off-hook you hear interrupted dial tone.
