  CDRs are instrumental in detecting and preventing fraudulent activities within a network. By analyzing call patterns and anomalies, telecom operators can identify suspicious behavior, unauthorized access, or other security threats, enhancing overall network security.
• Billing and Revenue Assurance
  Telecom service providers leverage CDRs for accurate billing and revenue assurance. The detailed information within CDRs allows for precise billing calculations, making sure customers are billed correctly for the services they use and minimizing revenue leakage.
