Which two configurations should you enable on Cisco Unified Communications Manager for integration with Cisco Unified Communications Manager IM and Presence Service? (Choose two.)

The Cisco CallManager service is the core call-processing engine on CUCM and must be running so that IM and Presence Service can retrieve user and device data via the AXL/SOAP interface. Without this service active, CUCM cannot respond to the synchronization requests that IM and Presence Service depends on. It is a foundational prerequisite before any integration steps can succeed.

End users must be explicitly enabled for IM and Presence in CUCM Administration so that their accounts are synchronized to the IM and Presence Service node. This enablement assigns each user a JID and allows the IM and Presence Service to manage their availability status and IM capabilities. Without this step, users do not appear in the IM and Presence database and cannot authenticate with a presence client.

Creating an Application User and associating presence-enabled endpoints with it is not a required step for standard CUCM-to-IM-and-Presence integration - end-user device association handles this relationship.

The Cisco CARWeb service supports CDR Analysis and Reporting functions and plays no part in establishing integration between CUCM and IM and Presence Service.

The Cisco Extended Functions service supports features such as the Quality Report Tool and software conference bridges and is not required for IM and Presence Service integration.
