/mcpInteraction with Do Not Disturb Feature Multilevel Precedence and Preemption (phones that are running SCCP) and Cisco Emergency Responder calls override DND. Multilevel Precedence and Preemption and Cisco Emergency Responder calls get presented normally, and the phone ring is supported on both SCCP and SIP. MLPP and CER For the originating side, callback overrides DND. When the activating device is on DND mode, the callback notification (both audio and visual) is still presented to the user. For the terminating side, DND overrides callback as follows: • When the terminating side is on DND Ringer Off, the Callback Available screen is sent after the terminating side goes off hook and on hook. • When the terminating side is on DND Call Reject, and is available, a new screen is sent to the activating device as "<DirectoryNumber> has become available but is on DND-R" if the activating device is in same cluster. Callback available notification is sent only after the terminating side disables DND Call Reject. Call Back 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. Pickup Notification If a device in a Hunt List has DND Ringer Off activated, the call is still presented to the user. However, the DND Incoming Call Alert settings would still apply. If a device in a Hunt List has DND Call Reject activated, any calls to that Hunt List will go to the next member and will not get sent to this device. Hunt List For Extension Mobility, the device profile settings include DND incoming call alert and DND status. When a user logs in and enables DND, the DND incoming call alert and DND status settings get saved, and these settings get used when the user logs in again. Note When a user who is logged in to Extension Mobility modifies the DND incoming call alert or DND status settings, this action does not affect the actual device settings. Extension Mobility Restrictions Some restrictions apply to DND usage, depending on the phone or device type in use. • The following phone models and devices that are running SCCP support only the DND Ringer Off option: • Cisco Unified IP Phone 7940 • Cisco Unified IP Phone 7960 • Cisco IP Communicator Feature Configuration Guide for Cisco Unified Communications Manager, Release 15 and SUs 567 Presence and Privacy Features Restrictions
