FCC Cracking Down on Another Loophole Used by Robocallers
Apr 29, 2025, 12:15 PM by Rich Brome @rbrome.bsky.social
The FCC is proposing that all phone calls within the US must maintain caller ID authentication info even when passing through non-IP networks. This will will close a key loophole used by malicious robocallers to disguise their identity and avoid detection. There are three technical proposals to meet this new requirement, two of which the FCC is giving its blessing to, and a third it is still accepting comment on. Most voice traffic moves through IP-based networks, and the FCC has already implemented rules requiring "STIR/SHAKEN" caller ID authentication for that traffic, one of many steps the FCC has taken in the last decade to tackle the scourge of malicious robocalls and scam calls.
