This letter marks approximately eight months since fifty-one state attorneys general and twelve leading voice service providers (“VSPs”) promulgated the Anti-Robocall Principles (“Principles”) in order to more effectively combat the unwanted and illegal robocalls inundating the American people. The collaboration reflected in the Principles is intended to halt the onslaught of such calls and to “aid the State Attorneys General in identifying and prosecuting illegal robocallers.” The state attorneys general and telecom industry participants also supported efforts by the U.S. Congress to enact the TRACED Act, which focuses on tracing illegal robocalls in addition to other sweeping anti-robocall measures.
