Chapter 19 Do Not Disturb
Overview of Do Not Disturb Architecture
• Beep Only—For an incoming call, this option causes the phone to play a beep tone only.
• Flash Only—For an incoming call, this option causes the phone to display a flash alert.
You can configure DND Incoming Call Alert on a per-device basis and also configure it on the Common
Phone Profile window for group settings. If you do not set up the configuration at the device level, the
Common Phone Profile settings get used.
Overview of Do Not Disturb Architecture
This section provides an overview of DND architecture for both SIP and SCCP devices and includes the
following topics:
• DND Status Notification for SIP Devices, page 19-3
• DND Status Notification for SCCP Devices, page 19-3
DND Status Notification for SIP Devices
Cisco Unified Communications Manager supports Do Not Disturb that a SIP device initiates or that a
Cisco Unified Communications Manager device initiates. A DND status change gets signaled from a SIP
device to Cisco Unified Communications Manager by using the SIP PUBLISH method (RFC3909). A
DND status change gets signaled from a Cisco Unified Communications Manager to a SIP device by
using a dndupdate Remote-cc REFER request. Cisco Unified Communications Manager can also publish
the Do Not Disturb status for a device, along with the busy and idle status for the device.
DND Status Notification for SCCP Devices
Cisco Skinny Client Control Protocol (SCCP) supports Do Not Disturb requests that an SCCP device
initiates or that a Cisco Unified Communications Manager device initiates. A DND status change gets
signaled from an SCCP device to Cisco Unified Communications Manager by using SCCP messaging.
