Cisco Unified IM and Presence (IM&P)

Cisco's on-premises instant messaging and presence service that integrates with CUCM and uses XMPP for clients.

Definition

IM and Presence provides availability status, one-to-one and group chat, persistent chat rooms and federation with other organizations or platforms. It runs in a cluster of nodes in subclusters tied to a CUCM cluster, synchronizes users from CUCM and uses SIP for presence from phones. Clients such as Jabber and Webex App connect using XMPP.

Example

A user's presence turns to On a call when her desk phone goes off-hook, based on CUCM line state shared with IM and Presence.

Exam tip

IM&P uses XMPP for clients and SIP to CUCM; high availability is configured per subcluster.
