A newly filed patent (Publication Number: US20240040038A1) describes a computing system designed for the automated detection of scam calls. The system includes at least one hardware processor and memory storing instructions that enable the system to receive phone calls routed away from a subscriber, simulate the subscriber's speech to elicit responses from the caller, classify the caller as a scam or non-scam based on the responses, and process the call accordingly. This processing may involve automatically disconnecting the call if the caller is identified as a scammer or displaying a notice on the subscriber's mobile device.

Furthermore, the patent outlines a method and computer-readable medium storing instructions for implementing the automated scam call detection system. The method involves receiving audio/video communications routed away from a subscriber, simulating the subscriber's speech to elicit responses, classifying the caller as a scam or non-scam based on the responses, and processing the communication accordingly. This processing may include automatically disconnecting the communication or displaying a notice on the subscriber's mobile device. The system also generates a database entry to track scam callers and can route future communications away from these identified scammers based on the database entry. The classification of the caller as a scam or non-scam is determined using subscriber-specific information stored in the subscriber's profile.
