Complete call detail records (CDRs) provide extensive information about a phone call, including the call's route, originating device, and errors, crucial for network maintenance and investigations.
For businesses and call centers, CDRs reveal signs of fraud, as hackers often target vulnerable VoIP systems, necessitating diligent monitoring to prevent unwanted calls.
To access CDRs, users must navigate their VoIP provider’s web portal, where records are listed under settings like Call Logs or Call History, with various visible fields.
CDRs contain critical details such as origin number, receiver number, call duration, and location, which can differ based on user permissions and provider capabilities.
