CDR stands for "Call Detail Record," which refers to a detailed log or record containing information about a telephone call or communication session, including both incoming and outgoing calls. It is typically generated by telecommunication service providers or network operators. A CDR provides a comprehensive account of various aspects related to the call, such as the source and destination phone numbers, call duration, call start and end time, call quality, call type (voice, video, or data), call route, and any additional parameters.
CDRs are primarily utilized for billing and billing verification purposes, enabling service providers to accurately bill customers and track their usage of telecommunication services. Additionally, CDRs play a crucial role in troubleshooting and analyzing network performance, as they offer valuable insights into the quality of service, call drops, latency issues, or any abnormalities within the network infrastructure. This data can then be analyzed to optimize network performance, improve call routing, or identify potential issues that may require maintenance or upgrades.
Moreover, CDRs find extensive applications in fraud detection and prevention, assisting service providers in identifying and mitigating fraudulent activities such as call and credit card fraud. Furthermore, in the field of law enforcement and national security, CDRs serve as crucial evidence in investigations and legal proceedings, as they provide valuable information about communications between individuals or groups.
In summary, CDRs are comprehensive records that document various data points related to telecommunication calls, facilitating billing, troubleshooting, network optimization, fraud detection, and legal investigations.
