Get Ready for December 15 Enforcement: Join the Somos & TelcoBridges Webinar on FCC DNO Compliance

Dec 04, 2025

The FCC’s new Do Not Originate (DNO) blocking rules take effect on December 15, 2025, and they raise the bar for every U.S. service provider. Under these requirements, providers must check outbound calls against a DNO list, making the use of a reasonable DNO list a core part of compliance.

That deadline is approaching fast. To help providers prepare with clarity and confidence, Somos and TelcoBridges are hosting a joint webinar that focuses on what the mandate requires and how to implement DNO checks in real-world networks using a ready-to-deploy solution.

Join Telco Bridges’ CEO, Maximilien Le Sieur, and Somos’ VP, Commercial Sales and Strategic Partnerships, Bill LaRuffa to learn:

•  What “reasonable” DNO compliance looks like in practice and why it matters operationally, not just legally

• How providers can operationalize DNO blocking and strengthen robocall mitigation ahead of the December 15, 2025 effective date

• How to integrate real-time DNO checks into outbound traffic flows using TelcoBridges’ DNO Module with ProSBC and Tmedia Gateways, powered by the industry’s most comprehensive DNO dataset, Somos’ RealNumber® DNO for stronger verification.

If you are building your compliance plan now, this is the practical walkthrough you want before the deadline.
