Webinar Recap: How to Achieve FCC Do Not Originate Compliance

Jan 08, 2026

The Federal Communications Commission’s (FCC’s) Do Not Originate (DNO) blocking rules took effect on December 15, 2025, requiring all U.S. voice service providers to check outbound calls against a reasonable DNO list to prevent illegal, spoofed and high-risk traffic from reaching consumers. This expanded mandate applies to all providers in the call path, not just gateway providers, and represents a major step in robocall mitigation efforts.

To help providers operationalize the mandate, TelcoBridges, a leading provider of carrier-grade hardware and software, hosted the webinar “How to Achieve FCC Do Not Originate Compliance,” featuring Bill LaRuffa, VP of Commercial Sales and Strategic Partnerships at Somos, and Maximilien Le Sieur, CEO of TelcoBridges. They unpacked what “reasonable” means in practice and emphasized that compliance is not just having a list; it is enforcing DNO checks in the outbound call flow and maintaining a program that is defensible, consistent and operational, supported by the TelcoBridges DNO Module and Somos’ RealNumber® DNO.

Key Takeaways from the Webinar

1. DNO is a compliance and fraud mitigation foundation

DNO blocking is now a mandatory part of robocall mitigation under the FCC’s expanded requirements. As the webinar reinforced, DNO is not a standalone checkbox. It is a practical control that helps stop spoofing and illegal traffic before it ever leaves your network, strengthening customer trust and downstream network confidence.

2. “Reasonable” means practical and defensible

A central focus of the webinar was how providers should think about the FCC’s use of the word “reasonable.” The presentation emphasized that a reasonable DNO list is not a static spreadsheet. It should support operational readiness and defensibility through:

• Coverage that meaningfully addresses non-originating number categories commonly exploited for spoofing and fraud

• Regular, reliable updates with clear ownership

• Consistent enforcement across outbound call paths

• Lightweight documentation that clearly explains what you use, how it is updated and where it is applied

3. Real-world implementation matters as much as policy

The webinar offered practical guidance on implementation because what matters most is how DNO checks operate in your outbound call flows. Speakers highlighted common challenges providers face, such as inconsistent enforcement across platforms, uneven deployment across vendors and manual processes that lead to drift. The session emphasized that these gaps are fixable with the right data and a clear implementation plan.

4. How TelcoBridges operationalizes DNO blocking

Maximilien Le Sieur highlighted the technical side of compliance and the importance of deploying DNO checks where they have the most impact. The webinar outlined how the TelcoBridges DNO Module integrates with ProSBC and Tmedia Gateways to perform real-time DNO checks at key call-processing points. This gives providers a practical path to operationalize the FCC’s requirements without overhauling their core infrastructure.

5. Why data quality matters: RealNumber® DNO

Bill LaRuffa emphasized that the quality and breadth of a DNO dataset can directly impact a provider’s ability to meet “reasonable” expectations while improving fraud outcomes. The webinar highlighted Somos’ RealNumber® DNO as an authoritative DNO dataset built to support compliance and reduce spoofing and illegal traffic. RealNumber® DNO offers comprehensive coverage across key DNO categories and supports the operational realities providers face, including the need for dependable updates and efficient integration.

Practical Next Steps for Providers

If your organization has not yet completed its DNO implementation, or if you are reviewing your posture after the effective date, the webinar recommended focusing on a few high-impact actions:

• Assess your current DNO posture and identify where DNO checks are applied and where gaps remain

• Select and integrate a comprehensive dataset that supports the FCC’s definition of a reasonable DNO list

• Implement consistent enforcement across outbound call paths, including alternate routes and vendor-managed environments

• Document your program so you can clearly explain how your DNO list is built, updated and enforced

Don’t Wait: Watch On Demand and Take Action

The FCC’s DNO mandate is now live, and service providers must demonstrate they are operating with a reasonable and enforceable DNO list. The Somos and TelcoBridges webinar offered a clear, practical guide to achieving compliance by pairing regulatory clarity with implementation guidance.
