A technician is preparing to activate the needed services in Cisco Unified Communications Manager to integrate with an IM and Presence server. Which four services must be enabled? (Choose four.)

Cisco TFTP serves device configuration files needed by clients; Cisco AXL Web Service provides the API that IM and Presence uses to synchronize user, device, and line data from CUCM; Cisco CTI Manager enables CTI-based presence status updates; and Cisco Unified Communications Manager is the core call-processing service that must be active for any integration to function.

Cisco Messaging Interface is used for SMDI integration with legacy voicemail systems and has no role in IM and Presence Server integration.

Cisco Intercluster Lookup Service (ILS) enables digit analysis across multiple CUCM clusters and is not required for IM and Presence synchronization.

Cisco Extended Functions provides features such as the Quality Reporting Tool (QRT) and is not a dependency for IM and Presence integration.

Cisco Directory Sync is not a CUCM-side service required for IM and Presence integration; user synchronization is handled via AXL.
