Cisco Unity Connection (CUC)

Cisco's on-premises voicemail, unified messaging and IVR platform that integrates with CUCM and other call control systems.

Definition

Unity Connection provides voicemail boxes, auto attendants, call handlers, speech-enabled directory access and integration with Microsoft Exchange or Microsoft 365 for single inbox. It is deployed as a two-node active/active cluster (publisher and subscriber) and integrates with CUCM using SCCP voicemail ports or a SIP trunk. Users, classes of service and templates can be imported from CUCM via AXL or from LDAP.

Example

Callers forwarded on no-answer from CUCM reach Unity Connection over a SIP trunk and hear the user's standard greeting.

Exam tip

Know the integration methods (SCCP ports versus SIP trunk) and how call routing rules decide what callers hear.
