Explanation:

When you configure Presence in Cisco Unified Communications Manager Administration, an
interested party, known as a watcher, can monitor the real-time status of a directory number or
SIP URI, a presence entity, from the device of the watcher.

presence groups. A presence group contains watchers and the destinations that can be monitored
by the watchers in the group. To allow watchers in one group to monitor directory numbers in other
