This widespread implementation helps protect consumers against malicious spoofed robocalls and helps law enforcement track bad actors. The STIR/SHAKEN standards serve as a common digital language used by phone networks, allowing valid information to pass from provider to provider which, among other things, informs blocking tools of possible suspicious calls.
