Presence Indications
Visibility for Presence-enabled call and directory lists can be limited through the use
of Partitions and subscribe Calling Search Spaces. A Subscribe CSS is specific to a
Presence monitoring system: If the DN to be watched is in the watcher's Subscribe
CSS, presence indications are visible; if it is not, the DNs appear as Unregistered sta-
tus to the watcher.
■
Presence Groups allow different sets of watchers to be assigned (or denied) permis-
sion to watch the Presence status of DNs in other Presence Groups. Phones, DNs, and
users can be assigned to Presence Groups. All users are in the standard Presence
Group by default, but can be assigned to custom Presence Groups as desired. The en-
terprise parameter configuration page
Inter-Presence Group Subscribe Policy
set-
ting defines the default setting for whether Presence Groups have permission to
watch each other's Presence status or not; this setting may be overridden in the Pres-
ence Group settings. Members of a Presence Group are always able to watch other
members of the same group, unless the Subscribe CSS prevents the subscription. The
Subscribe CSS and Presence Group settings may be used independently of one an-
other or together. If both are used, both must allow a subscription in order for a
watcher to monitor the Presence status of a DN.
■
Inter-Presence Group settings apply only to BLF Call Lists and Directories and do not
affect BLF Speed Dials.
