Explanation
The three components that are installed from the Cisco CRS Installer media are the Cisco CRS Engine, the Cisco Recording, and the MS SQL Server. The Cisco CRS Engine is the core component of the Unified CCX system that provides the call processing, scripting, and application integration functions. The Cisco Recording is the component that enables the recording and playback of agent calls for quality monitoring and training purposes. The MS SQL Server is the component that provides the database services for the Unified CCX system, such as storing configuration data, historical data, and agent data. The other components listed are not installed from the Cisco CRS Installer media. The iPlanet Web Server is not used by the Unified CCX system, as it uses the Apache Tomcat Web Server instead. The Cisco IP Telephony Windows 2000 Server OS is not a component of the Unified CCX system, as it uses the Linux-based Cisco Unified Communications Operating System. The Cisco Unified CallManager is not a component of the Unified CCX system, but a separate product that provides the call control and signalingfunctions for the IP telephony network.
