The news: Phone companies are now prohibited from accepting calls from providers that did not comply with the FCC’s deadline to register in the Robocall Mitigation Database, per Ars Technica.
Here’s how it works: The FCC’s solution, known as the STIR/SHAKEN protocol, is a first step to stopping spam callers from pretending to be someone else.
It works at the network level to automatically show a caller’s true phone number.
What’s the catch: STIR/SHAKEN isn't a cure-all. The technology’s limitations, particularly with older copper landlines or TDM-based networks, make it difficult to implement.
