As widely reported, all 50 state attorneys general and 12 major voice service providers have signed an agreement to combat illegal and unwanted robocalls and caller ID spoofing. The agreement provides for state AG cooperation with voice service providers that implement eight "anti-robocall principles." Those principles are: Offer Free Call Blocking and Labeling; Implement STIR/SHAKEN; Analyze and Monitor Network Traffic; Investigate Suspicious Calls and Calling Patterns; Confirm the Identity of Commercial Customers; Require Traceback Cooperation in Contracts; Cooperate in Traceback Investigations; and Communicate with State Attorneys General.
