Cisco Unified CallManager is the call-processing component of the Cisco Unified Communications system. Cisco Unified CallManager extends enterprise telephony features and capabilities to packet telephony network devices such as IP phones, media processing devices, voice-over-IP (VoIP) gateways, and multimedia applications. Additional services such as unified messaging, multimedia conferencing, collaborative contact centers, and interactive multimedia response systems interact with the IP telephony solution through Cisco Unified CallManager application programming interfaces (APIs). Cisco Unified CallManager is installed on Cisco MCS 7800 Series Media Convergence Server platforms and selected third-party servers. It has a suite of integrated voice applications and utilities, including the Cisco Unified CallManager Attendant Console (an ad-hoc conferencing application), the Cisco Unified CallManager Bulk Administration Tool (BAT), the Cisco Unified CallManager Call Detail Record (CDR) Analysis and Reporting tool, the Cisco Unified CallManager Real-Time Monitoring Tool (RTMT), the Cisco Unified CallManager Auto-Attendant (CM-AA), the Tool for Auto-Registered Phone Support (TAPS), and the Cisco Unified CallManager Assistant application.

Cisco Unified CallManager Version 4.3 is an enterprise IP telephony call-processing solution that is scalable, distributable, and highly available. Multiple Cisco Unified CallManager servers are clustered and managed as a single entity. Cisco Unified CallManager clustering yields scalability of from 1 to 30, 000 IP phones per cluster, load balancing, and call-processing service redundancy. Interlinking multiple clusters allow system capacity to reach 1 million users in a system of more than 100 sites. Clustering aggregates the power of multiple, distributed Cisco Unified CallManager installations, enhancing the scalability and accessibility of the servers to phones, gateways, and applications-and triple call-processing server redundancy improves overall system availability. Cisco Unified CallManager Version 4.3 allows customers to migrate to an operating system based on Microsoft Windows Server 2003. To ensure a smooth migration, this version does not include any new features. Cisco Unified CallManager Version 4.3 includes all the features of Cisco Unified CallManager 4.2(3), for example, enhanced call park, and the ability to log in and out of hunt groups. Cisco Unified CallManager 4.3 continues to utilize Microsoft SQL Server 2000 as its database.
