AT&T and T-Mobile team up to fight scam robocalls
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.
