As we previewed recently, the FCC adopted a set of rule amendments through a Third Report and Order for its “call blocking by default” framework on July 16, 2020. These rules focus on two safe harbors potentially shielding voice service providers from liability when they block calls that fail the SHAKEN/STIR authentication framework or that originate from “bad-actor upstream voice service providers.” These rules also generally provide for protection of “critical calls,” and condition safe harbors on having a no-cost, streamlined solution designed to remedy blocking errors, without defining what constitutes an “error.”
The rules as adopted had few substantive changes from the draft version that was released prior to the FCC’s July 2020 Open Meeting. First, the FCC added a clarification that the safe harbor that allows voice service providers to block calls based on “bad-actor upstream voice service providers” is not intended to “affect[] the private contractual rights a downstream provider has to block or refuse to accept calls pursuant to its agreements with wholesale customers.” This clarification suggests that the FCC does not intend this safe harbor to be the only permissible provider-based blocking under the FCC’s rules. For example, the FCC has long recognized that consumer consent or opt-in could be a valid basis for call blocking.
