Call Detail Records (CDRs) contain vital information about call activity, such as origin and receiver numbers, call time, duration, and location, and are crucial for identifying fraudulent call schemes like traffic pumping and toll fraud. By accessing CDRs through VoIP or call center software portals, organizations can analyze data patterns, automate CDR analysis to detect abnormalities, prevent fraud schemes like PBX hacking, International Revenue Share Fraud (IRSF), and domestic traffic pumping, and take proactive measures to avoid financial losses by setting up alerts and blocking high-risk destinations based on CDR data. ```
