Detecting New Call Detail Records Files and Transferring to CDR Repository Node

E.

The correct answer is E. Cisco CDR Agent.

Cisco Unified Communications Manager (CUCM) generates Call Detail Records (CDRs) for every call that passes through the system. CDRs contain information about the call, including calling and called party numbers, call duration, call direction, and more. These records are used for billing, troubleshooting, and reporting purposes.

To manage CDRs, CUCM uses a service called the CDR Agent. The CDR Agent is responsible for detecting new CDR files and transferring them to the CDR Repository node. The CDR Repository node is typically a standalone server that stores CDRs and provides reporting capabilities.

When CUCM generates a new CDR file, it saves it to the local file system on the CUCM server. The CDR Agent monitors this directory and detects when new files are added. It then reads the file, extracts the CDR data, and sends it to the CDR Repository node using the Simple Object Access Protocol (SOAP).

The CDR Agent also provides options for configuring CDR retention policies, enabling/disable CDR generation, and configuring CDR transfer settings. These settings are typically configured in the CUCM Administration interface under System > Service Parameters.

In summary, the Cisco CDR Agent is responsible for detecting new CDR files and transferring them to the CDR Repository node. This service is critical for managing CDRs and providing reporting capabilities in CUCM.
