Understanding Presence
Presence is an indication of the availability of an individual at a point in time and their readiness to
communicate across a set of services such as telephony and instant messaging. The person's
status or availability is represented using states like Available, Busy, and Away. To enable this
feature, the Avaya Room System XT Series endpoint registers to an Extensible Messaging and
Presence Protocol (XMPP) server to publish its own presence status and to view the presence
status of other contacts, such as other XT Series endpoints or devices registered to the Presence
server.
For example, a user Alice can publish her own status when she registers to the Presence server.
The Presence server is notified every time her status changes. A user Bob can subscribe as a
watcher to the Alice contact and see her status. When Bob subscribes as a watcher to the Alice
contact, Alice may be able to approve or reject Bob's request to be a watcher. Alternatively,
depending on the configuration of the Presence server, Bob's subscription may be granted
automatically. Alice can also ignore Bob's request or revoke his access. Bob can unsubscribe from
being a watcher at any time.
