DoT Launches System to Block International Scam Calls

• 08 Oct 2024

In October, 2024, the Department of Telecommunications (DoT) introduced a two-phase system to detect and block incoming scam and spam calls from international numbers, aiming to protect telecom subscribers across India.

Key Points

• Two-Tiered System for Blocking Scam Calls: The new system involves telecom service providers (TSPs) preventing international spoofed calls within their networks in the first phase, while the second phase will focus on eliminating spoofed calls from other networks.
• Centralized Blocking System: A centralized system, expected to be launched soon, will tackle all remaining spoofed calls across TSPs, further securing the Indian telecom network from fraudulent international calls.
• Telecom Resources Safeguards: DoT has previously set up a Digital Intelligence Unit (DIU) to combat cybercrime and launched the Sanchar Saathi portal for citizens to block or track lost mobile phones, enhancing telecom security.
• AI-Based Fraud Detection: Using AI tools, DoT identifies and disables mobile connections acquired through fraudulent KYC documents, while TRAI mandates AI/ML systems to detect spam calls and messages from unregistered telemarketers.
• Proposed Mandatory Caller ID System: TRAI is considering introducing a caller ID system (CNAP) to reduce unwanted calls and differential tariffs for high-volume callers or message senders to curb spam activities.
