For the DND Ringer Off option, only visual notification gets presented to the device. For the DND Call Reject option, no notification gets presented to the device. For the terminating side of the call, Do Not Disturb overrides call back: ✑ When the phone that terminates the call uses DND Ringer Off, the Callback Available screen will be displayed on the phone after the terminating side goes off hook and on hook. When the phone that terminates the call has DND Call Reject enabled but the phone becomes available (goes off hook and on hook), a new screen will be presented to the originating device as "<Extension> has become available but is on DND-R". Callback available notification will be sent only after the terminating side disables DND Call Reject.
