STIR/SHAKEN Protocols Address Caller ID Spoofing

/ 1 min read

📞🔒 STIR/SHAKEN Protocols Aim to Combat Caller ID Spoofing. The STIR/SHAKEN framework is designed to address the growing issue of caller ID spoofing, which is often exploited by robocallers to disguise their identities. STIR (Secure Telephone Identity Revisited) adds digital certificates to VoIP call headers, while SHAKEN (Signature-based Handling of Asserted information using toKENs) provides guidelines for handling calls with incorrect or missing STIR data. The Federal Communications Commission (FCC) mandated U.S. carriers to implement these protocols by June 30, 2021, with similar requirements set by the Canadian Radio-television and Telecommunications Commission (CRTC). Despite these efforts, the effectiveness of STIR/SHAKEN in fully eliminating robocalls remains to be seen, as the system relies on a chain of trust among service providers.
