DoT System to Detect and Block Spoofed International Calls
Hindustan TimesUnion Minister for Communications Jyotiraditya Scindia launches a new system to block spoofed international calls. The system, called the International Incoming Spoofed Calls Prevention System (DoT), can detect and block spam international calls that display Indian numbers as the caller ID. The system is implemented in two phases. In the first phase, a telco checks whether the subscriber is outside India and making a call. If the subscriber is outside India, Airtel will let the call through, but if its data shows that the genuine subscriber is within India, the call will be dropped. In the second phase, an integrated database is used to check for genuine subscribers. The system identified and blocked 13.5 million incoming international calls with Indian phone numbers as spoofed calls.
