A call detail record (CDR) is a file that contains information about a telephone call or other telecommunication event. It captures details created by a telephone exchange. It contains information about the phone numbers of the caller and receiver as well as the time and date when the call was made, the duration of the call, and the type of call. These records allow the telecommunications service providers to analyze call traffic patterns and performance and identify potential issues with the networks.
Call detail records are also important for the billing process because service providers can use them to accurately bill the customers who make the calls. Furthermore, service providers can use CDRs to analyze call routing. That way, they can optimize and ensure that all calls are routed effectively.
