WASHINGTON—Federal Communications Commission Chairman Ajit Pai on Nov. 5 wrote the chief executives of major telephone service providers and other companies, demanding they launch a system no later than 2019 to combat billions of “robocalls” and other nuisance calls received monthly by American consumers.
In May, Pai called on companies to adopt an industry-developed “call authentication system” or standard for the cryptographic signing of telephone calls aimed at ending the use of illegitimate spoofed numbers from the telephone system. Pai’s letters seek answers by Nov. 19 on the status of those efforts.
