Cybersecurity Policy Report, VoIP Provider Faces FCC Punishment Over Robocalls, (Mar 13, 2026)

By Lynn Stanton

The FCC’s Enforcement Bureau has issued a final determination order and removal order against Belthrough LLC, finding that the company failed to comply with Commission rules regarding the transmission of illegal traffic and directing that all providers immediately downstream from Belthrough begin blocking traffic from the company within 30 days.

“Downstream providers may choose to initiate blocking sooner than 30 calendar days from the release of the Final Determination Order if, prior to initiating blocking, they provide the Commission with notice and a brief summary of the basis for their determination that the provider failed to effectively mitigate illegal traffic within 48 hours of being notified by the Commission or failed to implement effective measures to prevent new and renewing customers from using its network to originate illegal calls,” the bureau said, FCC, Final Determination Order and Removal Order, Dkt. 22-174 (March 12, 2026).

The bureau also removed Belthrough’s certification from the FCC’s robocall mitigation database (RMD). That action triggers a mandate for all voice service providers and intermediate providers to cease accepting calls directly from Belthrough within two business days of today’s release of the removal order.

Belthrough is not allowed to refile its RMD certification without the prior approval of the Enforcement and Wireline Competition bureaus.

“Other than acknowledging receipt of the Notice, Belthrough took no action in response to either the Notice or the Initial Determination Order,” which are the earlier steps in the FCC’s mandatory call blocking framework established in its 2023 gateway provider order, the Enforcement Bureau noted.

The bureau issued an initial determination order and order to show cause last month (CPR, Feb. 23) and a notification of suspected illegal traffic last year.
