Identification is insufficient without accountability.

SHAKEN/STIR identifies whether or not a given number is originating from a specific network, but without knowing whether that's an approved network, rejecting unapproved-origin calls, or tracking how much unapproved traffic a given network is emitting and penalising it for this, the information isn't actionable.

"Measure it harder" doesn't solve problems. The information must direct meaningful action.
