This lesson introduces and describes the role, architecture, hardware and software requirements, and the licensing model of the CUCM.
Understanding the role that CUCM plays in a converged network from a system, software, and hardware perspective is necessary for successfully installing and configuring CUCM. A Cisco Unified Communications deployment relies on Cisco Unified Communications Manager (CUCM) (formerly known as Cisco Unified CallManager) for its call-processing and call-routing functions.
