Report on Combatting Illegal Robocalls, FCC Asks NANC WG

The FCC Wireline Bureau directed the North American Numbering Council call authentication trust anchor working group to submit reports and suggest best practices on combating illegal robocalls, said a charge letter Tuesday. The first report, due Oct. 15, should include deployment of secure telephone identity revisited and signature-based handling of asserted information using tokens by small voice service providers "during the pendency of their extension from the Stir/Shaken implementation deadline," the letter said. The bureau asked NANC to identify barriers preventing small providers from implementing the Stir/Shaken framework and available technological solutions. The second report, due Feb. 15, should include best practices on how terminating voice service providers can protect subscribers using caller ID authentication information. By June 15, 2022, a document should include steps to encourage adoption of techniques by policymakers and providers in other countries to combat robocalls.
