Which of the following features are supported by UCM IM and Presence Service in either IM-only mode or Cisco Unified Communications mode? (Choose three.)
- audio calls
- IM
- Presence
- video calls
- XMPP integration
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 IM-only 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 call and press the phone icon. However, IM messaging will be the only available option if UCM is configured in IM-only 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.
