Full Form of CDR
What is CDR?
A Call Detail Record (CDR) is a data record produced by a telephone exchange or other telecommunications equipment that documents the details of a phone call or other communication transaction. In the Indian context, CDRs are crucial for telecom operators like Airtel, Jio, and BSNL to bill customers, manage network traffic, and detect fraud. They contain information such as calling and called numbers, call duration, timestamp, and location of the caller. CDRs play a pivotal role in law enforcement investigations, where authorities legally request them to track suspects, verify alibis, or combat cybercrime. The Department of Telecommunications mandates that operators retain CDRs for a specified period. CDRs are also used in network planning and quality of service monitoring. For competitive exams like UPSC, SSC, or banking, understanding CDRs is relevant under topics of cyber law, digital evidence, and telecom regulations. The term is frequently encountered in news reports about high-profile cases involving call tracing. While CDRs provide valuable evidence, their use is governed by privacy laws and court orders to prevent misuse.
