Chapter 1 Overview Call Detail Records and Call Management Records Call Detail Records and Call Management Records Call Detail Records (CDRs) and Call Management Records (CMRs) get used for post-processing activities such as generating billing records and network analysis. When you install your system, the system enables CDRs by default. CMRs remain disabled by default. You can enable or disable CDRs or CMRs at any time that the system is in operation. The CDR Management (CDRM) feature, a background application, supports the following capabilities: • Collects the CDR/CMR files from the Cisco Unified Communications Manager server or node to the CDR Repository server or node. • Collects and maintains the CDR/CMR files on the server where you configure CAR. • Maintains the CDR/CMR files on the CDR Repository node or CDR server. • Allows third-party applications to retrieve CDR/CMR files on demand through a SOAP interface. • Accepts on-demand requests for searching file names. • Pushes CDR/CMR files from individual nodes within a cluster to the CDR Repository server or node. • Sends CDR/CMR files to up to three customer billing servers via FTP/SFTP. • Monitors disk usage of CDR/CMR files on the server where you configure CAR or on the CDR Repository server or node. • Periodically deletes CDR/CMR files that were successfully delivered. You can configure the amount of storage that is used to store flat files. Predefined storage limits exist. If the storage limits are exceeded, the CDR Repository Manager deletes old files to reduce the disk usage to the preconfigured low water mark. The post-processing applications can later retrieve the buffered historical data to re-get any lost, corrupted, or missing data. The CDRM feature, which is not aware of the flat file format, does not manipulate the file contents. CDRM includes two default services, the CDR Agent and the CDR Repository Manager, and one activate service, CDR onDemand Service. For more information, refer to the Cisco Unified Communications Manager Call Detail Records Administration Guide. Call Detail Record Analysis and Reporting Cisco Unified Serviceability supports Call Detail Record (CDR) Analysis and Reporting (CAR) and is is available in the Tools menu. CAR generates reports for Quality of Service (QoS), traffic, and billing information. For its primary function, CAR generates reports about the users of Cisco Unified Communications Manager and reports on system status with respect to 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. CAR processes the CDRs from flat files that the CDR repository service places in the repository folder structure. CAR processes CDRs at a scheduled time and frequency. By default, CDR data loads continuously 24 hours per day and 7 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. OL-22523-01 Cisco Unified Communications Manager Managed Services Guide 1-7
