Explanation:
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.http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/admin/6_1_1/ccmfeat/cmfsgd611/fs
