DoT blocked 90% incoming international spoof calls after launch of new prevention system spot

An indigenously developed International Incoming Spoofed Call Prevention System by the Department of Telecommunications along with telecom service providers has blocked 1.35 crore or 90% of all incoming international calls identified as spoofed calls in 24 hours of its launch.

These international calls, which appear to unsuspecting citizens as originating from India have dipped to about 4 lakhs per day, indicating the success of the system.

Following the implementation of the system, scammers abroad have switched to spoofing using international numbers. To counter this, the DoT has asked telcos to display “international calls” on all calls coming from outside India. One of the major service providers have already implemented this in its network, while others will soon follow suit, DoT said in a press statement.


The DoT has also asked TSPs to block traffic from such international carriers which are repeatedly sending spoofed calls to India. BSNL, Reliance Jio, and Bharti Airtel have blocked more than 20 such carriers who were handing over spoofed international calls.

The action follows the release of the Sanchar Saathi app through which citizens can report fraudulent calls to the DoT, based on which action has been taken.
