Overview
The international inbound telecom fraud detection system is designed to prevent unauthorized VoIP calls originating from overseas and terminating in Vietnam, safeguarding the revenue and reputation of telecom operators. The system employs simbox devices located in various countries to make VoIP calls to Android devices placed in Vietnam. Suspicious phone numbers are automatically detected through analysis of calling frequency and other unusual patterns.
Once an unauthorized number is identified, the system sends alert notifications and detailed call reports to telecom operators, enabling them to swiftly make decisions to block the number and prevent fraudulent calls. With real-time monitoring and fast response capabilities, the system significantly reduces international telecom fraud, protecting revenue streams and improving the quality of telecommunications services. This solution has been widely deployed, demonstrating high effectiveness in detecting and preventing unauthorized VoIP calls, ensuring the security and stability of the national telecommunications infrastructure.
