From TechCrunch: Two major U.S. carriers, AT&T and T-Mobile, announced this morning a plan to team up to protect their respective customer bases from the scourge of scam robocalls. The two companies will today begin to roll out new cross-network call authentication technology based on the STIR/SHAKEN standards — a sort of universal caller ID system designed to stop illegal caller ID spoofing.
Robocalls have become a national epidemic. In 2018, U.S. mobile users received nearly 48 million robocalls — or more than 150 calls per adult, the carriers noted.
A huge part of the problem is that these calls now often come in with a spoofed phone number, making it hard for consumers to screen out unwanted calls on their own. That’s led to a rise in robocall blocking and screening apps. Even technology companies have gotten involved, with Google introducing a new AI call screener in Android and Apple rolling out Siri-powered spam call detection with iOS 13.
