Explanation:
Instant message (IM), Presence, and Extensible Messaging and Presence Protocol (XMPP) integration are all
Cisco Jabber features that are supported by Cisco Unified Communications Manager (UCM) IM and Presence
Service in either IM-only mode or Cisco Unified Communications mode. The UCM IM and Presence Service
enables a company to reduce communications delays in project collaboration by providing real-time, always
available communications channels. For example, the IM and Presence Service supports persistent chat
rooms, which are chat rooms that remain available even after the last user exits the room, and the ability to
review IM history.
The UCM IM and Presence Service has three modes of operation: IM-only mode, Cisco Unified
Communications mode, and Microsoft Office Communicator and Microsoft Lync interoperability mode. In IMonly mode, Cisco Jabber and third-party XMPP clients can connect to and use UCM for IM and Presence
services. In Cisco Unified Communications mode, the IM and Presence Service supports IM, Presence, XMPP
federation, and audio and video calls. XMPP federation allows Cisco Jabber clients to communicate with clients
that are registered to a different Cisco Jabber cluster.
Neither the audio call feature nor the video call feature of Cisco Jabber is supported when UCM IM and
Presence Service is running in IM-only mode. To place an audio or video call from Cisco Jabber, a user will
typically click the Contacts button to search the list of contacts. Next, the user should click on the contact to calland press the phone icon. However, IM messaging will be the only available option if UCM is configured in IMonly mode.
In Microsoft Office Communicator and Microsoft Lync interoperability mode, UCM IM and Presence Service
enables users of Microsoft Office Communicator or Microsoft Lync to control Cisco IP phones.Cisco: Cisco Unified Communications Manager IM and Presence Service 9.0 Data Sheet
