T-Mobile, AT&T, Verizon: What steps are they taking to reduce robocalls?

The three largest US mobile providers (T-Mobile, Verizon and AT&T) have met the deadline for its adoption its new anti-spoofing protocol FCC. The regulatory requirement is designed for fight against robocalls, ie of the automatically recorded messages - voicemails, especially those that try to hide their phone numbers. The FCC aims to enable users to control authenticity of calls.

The committee states that its extensive adoption STIR / SHAKEN will reduce the effectiveness of forgery (spoofing), will help law enforcement to identify any malicious agents and, most importantly, allow mobile phone owners to check the authenticity of calls and identify unwanted users before they even call them. Such a Verizon and T-Mobile announced on June 30 that all calls coming from networks their comply 100% with the technology "STIR / SHAKEN" FCC, which is designed to show the caller's real phone number. Meanwhile, AT&T confirmed in "The Verge" that it also complies with the new regulations.

The FCC had set June 30 as the deadline for major telecommunications companies to implement the STIR / SHAKEN protocol developed when Ajit Pai was president of the FCC. On the other hand, the smaller telecommunications companies have a deadline until 30 June 2023, unless the FCC decides to shorten this period, which is currently being considered.

But what exactly does the new protocol do? Without it, the scam / spam callers can falsify their phone numbers to appear as local numbers. Thus, you are more likely to answer their calls. STIR / SHAKEN tries to change this by using public key encryption certificates sent by the original telephone service provider, with the keys verified by the termination service provider. If these match, then the call number has not been forged.

The FCC hopes that implementing this protocol will reduce the amount of spam, scams and robocalls that have turned your phone response into a whack-a-mole game. The commission said more than 1.500 voice service providers are in its robocall mitigation database, with more than 200 of them fully certified. "As of September 28, 2021, if the certification of a voice service provider does not appear in the database, intermediaries and voice service providers are prohibited from directly accepting the movement of the provider", said the FCC.

The protocol will help reduce, but not completely eliminate scams and robocalls. The old telephone systems that do not use Internet Protocols (IP) are exempt from the regulations and the system will not work with international calls. However, if a local caller ID appears on your phone, you can be sure that it is not a fake number behind which a scammer will be hiding.
