What does a call detail record (CDR) provide for troubleshooting purposes?

A call detail record (CDR) is crucial for troubleshooting because it captures detailed information about each call that is processed through a telecommunications system. This information includes timestamps, duration, origin and destination numbers, call type, and status.

When troubleshooting, network engineers and analysts rely on CDRs to identify issues such as call drops, delays, or failures. The data captured in CDRs helps them analyze patterns and pinpoint the exact moments when problems occur, facilitating effective diagnostics and resolution of issues.

While billing and analytical purposes are a significant aspect of CDRs, the granularity of the data allows for an understanding of network performance and user interactions that can lead directly to improved service or rectifying specific issues. This makes CDRs essential tools not just for billing, but also for effective troubleshooting and enhancing overall service quality.
