in IM-only mode? (Choose two.)

audio calls
B.
IM
C.
Presence
D.
video calls
E.
XMPP integration
Explanation:
Neither the audio call feature nor the video call feature of Cisco Jabber is supported when Cisco Unified
Communications Manager (UCM) instant message (IM) and Presence Service is running in IM-only 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 two modes of operation: IM-only and Cisco Unified Communications
mode. In IM-only mode, Cisco Jabber and third-party 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.
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.Cisco: Cisco Unified Communications Manager IM and Presence Service 9.0 Data
