FCC Moving Forward with Call Authentication

On 7 December 2017, the Federal Communications Commission (FCC) asked the North American Numbering Council (NANC) to provide advice on how the Trusted Anchor function should be defined and implemented in the pending STIR/SHAKEN call authentication system for Secure Telephone Identity.

They also asked the NANC to recommend a reasonable timeline for telecommunication service providers (TSPs) to deploy this call authentication system, including incentives or mandates that the FCC can put in place to ensure that the timeline is met.

The FCC asked the NANC to report back within four months of the letter, which would be 7 April 2018.

This is an important step in putting caller authentication in place so that TSPs can help customers regain trust in caller ID and avoid annoying, illegal robocalls.

Trusted Anchor Function

In the STIR/SHAKEN framework, the Trusted Anchor function includes:

  • Policy Administrator (PA) — the organization that runs the system
  • Governance Authority (GA) — a single entity that provides rules and standards to be followed by the PA and TSPs in using the system

The FCC letter mentions candidates for the GA role who have been suggested so far, including:

  • The FCC
  • The Alliance for Telecommunications Industry Solutions (ATIS)
  • A working group of the NANC

In their letter, the FCC asked the NANC to comment on the following:

  • Process for selecting the GA
  • Relationship between the FCC and the GA if separate
  • Process for selecting the PA

Working Group Appointments

On 8 February 2018, FCC commissioner Ajit Pai appointed members to the NANC working group on Call Authentication Trust Anchor Issues. Members represent a variety of TSPs, industry groups and technology companies, including our very own Jim Dalton, CEO and President of TransNexus, who was appointed a voting member.
