Ars Technica: FCC says it closed a loophole that many robocallers used to evade blocking

Ars Technica: FCC says it closed a loophole that many robocallers used to evade blocking. “Large voice providers were required to implement STIR/SHAKEN a year ago. But there was an exemption for carriers with 100,000 or fewer customers that would have given those smaller companies until June 30, 2023, to comply. The FCC voted in December to move that deadline up to June 30, 2022, because small phone companies were apparently carrying a disproportionately high number of illegal robocalls.”
