/mcpC H A P T E R 2 Overview The Cisco CDR Analysis and Reporting (CAR) tool generates reports for quality of service, traffic, user call volume, billing, and gateways. CAR uses data from Call Detail Records (CDRs), Call Management Records (CMRs), and the Unified Communications Manager database in order to generate reports. The CAR interface can be accessed under the Tools menu of Cisco Unified Serviceability. CAR is not intended to replace call accounting and billing solutions that third-party companies provide. You can find the companies that provide these solutions and that are members of the Cisco Technology Developer Program by searching the home page of the Cisco Developer Community. CAR does not handle iDivert calls (a feature that diverts calls to a voice-messaging system) and treats them as normal calls. The part of the call after the iDivert feature gets activated may not get charged to the correct party. Note • CDR Analysis and Reporting Overview, on page 5 CDR Analysis and Reporting Overview As its primary function, CAR generates reports about the users of Unified Communications Manager and generates reports on the system status about call processing. CAR also performs CAR database management activities. You can perform these tasks in one of the following ways: • Automatically configure the required tasks to take place. • Manually perform the tasks by using the web interface. You access CAR from the Tools menu of Cisco Unified Serviceability after you activate the appropriate services as described in the Activate CAR, on page 20. All CAR reports use CDR data. CAR processes the CDRs from flat files that the CDR Repository service places in the CDR repository folder structure. CAR processes CDRs at a scheduled time and frequency. By default, CDR data loads continuously 24 hours per day and seven days per week; however, you can set the loading time, interval, and duration as needed. In addition, the default setting loads only CDR records. CMR records do not get loaded by default.
