The deadline for all IP-based voice service provider networks to implement spoofed robocall defense standards was June 30. The FCC called the date the last significant extension.
The STIR/SHAKEN caller ID authentication standards are a common digital language used by phone networks. They allow valid information about a call to pass from provider to provider which informs blocking tools of possible suspicious calls by making it easier to detect spoofed calls. Caller ID authentication supports blocking tools, empowers investigators, and informs FCC efforts to disconnect illegal robocallers.
Specifically, facilities-based small voice service providers as well as gateway providers not subject to an extension must now implement the STIR/SHAKEN caller ID authentication framework in their IP networks. They join the voice carriers that have been required to implement STIR/SHAKEN over the last two years.
Various groups of providers have faced implementation deadlines over recent years, moving U.S. networks closer to full coverage:
- Largest Voice Service Providers – by June 30, 2021
- Non-Facilities-Based Small Providers – by June 30, 2022
- Facilities-Based Small Providers – by June 30, 2023
- Gateway Providers – by June 30, 2023
- Intermediate Providers – under FCC rules passed in March, intermediate providers that receive unauthenticated IP calls directly from domestic originating providers must use STIR/SHAKEN to authenticate those calls by December 31, 2023.
- Non-IP Networks – the FCC opened a proceeding to consider ways to implement caller ID authentication on non-IP networks, which cannot implement STIR/SHAKEN.
