What is Presence Management?
In terms of business telephony and communications, Presence is a status display in a contact list (also known as a “buddy list”) which indicates your availability status and that of your contacts. Thanks to presence management, it is possible to gain an instant overview of who is online, in a meeting, in DND mode or offline.
Through using presence information users who are connected within the same phone system or UC solution can immediately see whether a colleague is available or not. Rich Presence goes a step further and includes further information such as the state of a colleagues telephone, where they are working from etc., allowing users to see whether a colleague is on the phone, working from home and so on.
