Memo: Caller ID Authentication

October 20, 2020

Caller ID Authentication Second Report & Order

Also known as STIR/SHAKEN.

Summary

The FCC released its Second Report and Order on caller ID authentication requirements also known as STIR/SHAKEN on October 1, 2020. A few of the Order highlights are the extension of the STIR/SHAKEN implementation deadline from June 30, 2021 to June 30, 2023 for all small voice service providers (100,000 or fewer voice lines, including all affiliates), establishment of a robocall mitigation program and certification, and STIR/SHAKEN requirement for all IP portions of intermediate providers network by June 30, 2021.

In an effort to implement the TRACED Act and combat unwanted and illegal robocalls, several working groups developed standards to allow the authentication and verification of caller ID information for calls carried over IP networks. While the Secure Telephony Identify Revisited (STIR) working group produced protocols for authenticating caller ID information, other working groups produced the Signature-based Handling of Asserted information using toKENs (SHAKEN). STIR is the industry protocol of verifying that the call is legitimate, SHAKEN is the process to “sign off” on the call for downstream carriers.
