CDR

CDR, or Call Detail Record, is a digital log created by phone systems that captures information about phone calls. It includes details such as the phone numbers involved, call duration, start and end times, and the type of call (voice, SMS, data). CDRs are used by telecom companies and law enforcement to monitor network activity, troubleshoot issues, or investigate incidents. Think of it as a detailed diary of all phone call activities that happen on a network, providing valuable data for analysis and record-keeping.
