Indian Telcos Block 4.5 Million Spoof International Calls Daily

The Department of Telecommunications (DoT), in partnership with Telecom Service Providers (TSPs) has blocked 4.5 million spoofed calls as part of a new initiative to identify and block incoming international spoofed calls before they can reach Indian telecom subscribers. Fraudsters have been exploiting the Calling Line Identity (CLI) system to disguise foreign-origin calls as Indian numbers, leading to a rise in fake threats involving mobile disconnections, false accusations, and impersonation of government officials, Ministry of Communications said on Friday.

Centralised System to Strengthen Defence

In response, the DoT has rolled out a two-phase system to prevent such calls. The first phase, now active across all TSPs (Airtel, BSNL Vodafone Idea, Jio), blocks calls spoofed with numbers from within their networks.

“As of now, all four TSPs have successfully implemented the system. About one third of total spoofed calls at 4.5 million spoofed calls are being stopped from entering the Indian telecom network. The next phase, involving a centralised system that will eliminate the remaining spoofed calls across all TSPs, is expected to be commissioned shortly,” the Ministry said.
