Rather, they enable carriers to authenticate calls, after which consumers will be able to tell if a number is likely to be a robocall.
The FCC says STIR/SHAKEN should help to protect consumers against malicious caller ID spoofing, often used in robocall scams to trick us into answering our phones so telemarketers and/or scammers can bleat at us.
In a SHAKEN/STIR interaction, the originating caller's phone sends an authentication request along with their phone number to a STIR authentication service.
Carriers have also complained that SHAKEN doesn't tell them anything about the content of a call or whether it's legal.
Instead, all it does is authenticate the origination of the call path and the Caller ID information of individual calls.
