Back in March, the FCC ordered all carriers and phone companies to adopt the STIR/SHAKEN protocol by June 30th, 2021 as an effort to combat robocalls. Now, the commission has announced new rules to clarify carriers’ obligations regarding the technology’s implementation. One of those new rules, for instance, protects consumers from surprise charges. To be precise, it prohibits voice service providers from adding line-item charges to their bills for caller ID authentication.

The FCC is also requiring providers to upgrade their networks if they currently can’t implement STIR/SHAKEN, which is an Internet Protocol standard for IP-based networks. Otherwise, they’ll have to develop a non-IP caller ID verification solution. That said, the FCC will give small voice providers that can’t adopt the technology yet “limited extensions,” so long as they implement robocall mitigation programs.
