Question ID 12950	Which two call processing features have a lower priority than the Do Not Disturb settings on a Cisco IP phone? (Choose two.)
Option A	park reversion for a locally parked call
Option B	hold reversion
Option C	intercom
Option D	pickup notification
Option E	terminating side of a call back
Option F	originating side of a call back
Correct Answer	D,E

Explanation Explanation: 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 has become available but is on DND-R. Callback available notification will be sent only after the terminating side disables DND Call Reject.
