Which of the following will not be supported? (Select the best answer.)
A.
Cisco Jabber
B.
Cisco WebEx Social
C.
Microsoft Office Communicator desk phone control
D.
thirdparty XMPP clients
Explanation:
Of the available choices, Microsoft Office Communicator desk phone control will not be supported by Cisco
Unified Communications Manager (UCM) IM and Presence Service in instant message (IM)only mode. The
UCM IM and Presence Service enables a company to reduce communications delays in project collaboration by
providing realtime, 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: IMonly mode, Cisco Unified
Communications mode, and Microsoft Office Communicator and Microsoft Lync interoperability 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.
In IMonly mode, Cisco Jabber and thirdparty Extensible Messaging and Presence Protocol (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 IMonly 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 call
and press the phone icon. However, IM messaging will be the only available option if UCM is configured in
IMonly mode.
