Explanation
Cisco Unified Communications Manager (CUCM) handles call routing, call control, and signaling in a VoIP network.
The primary purpose of a Cisco Call Manager, now known as Cisco Unified Communications Manager (CUCM), is to manage call routing and signaling within a Cisco collaboration network. CUCM acts as the central software-based platform that handles call processing, signaling, device control, and call management functions for IP phones, video endpoints, gateways, and collaboration applications.
- CUCM provides call control, which includes establishing, maintaining, and terminating voice and video calls between endpoints.
- It manages call routing, ensuring that calls are directed to the correct destination based on dial plans, policies, and user preferences.
- CUCM handles signaling protocols (such as SCCP, SIP, MGCP, and H.323), enabling communication between endpoints and integrating third-party devices.
- Additional functions include device provisioning, feature administration (hold, transfer, conference), directory services, and integration with voicemail and messaging platforms.
Cisco Unified Communications Manager is responsible for call processing, signaling, and routing, enabling seamless voice and video communication across the enterprise network.
