The Devil’s in the Details
How to Block Calls from Carriers Not Listed in the FCC RMDB Starting 9/28


So, you’re registered in the FCC’s Robocall Mitigation Database (RMDB), and you documented what actions you’ve taken to implement STIR/SHAKEN and/or robocall mitigation. Now, the FCC says all intermediate providers and terminating voice service providers are prohibited from accepting traffic from carriers not listed in the RMDB as of September 28.


If you’re wondering how you are make that happen, you’re not alone. It will be challenging. If you’re receiving calls, you have to validate, in real-time, that the carrier that sent them the call is registered in the RMDB. But, the proper routing identifiers, such as the Operating Company Number (OCN) are not actually listed in the database.

We’re here to help. Learn about our Robocall Mitigation Database Solution, check out our Robocall Mitigation Cheat Sheet, and separate fact from fiction with our new tool: Robocall Mitigation Database: Myths vs. Facts. And don’t forget to reach out to us with questions at callerid@team.neustar.

STIR/SHAKEN Best Practice: How to Evaluate STIR/SHAKEN Attestations

By Lance Hood, Senior Product Management Director, Risk

Attestations serve as an important input to existing call analytics tools and incremental benefits, but they do not equate to a risk assessment of the person involved in the call. Inbound contact centers require more signals and analysis to determine caller treatment.

STIR/SHAKEN: The Role of Attestation in Authentication

By Lance Hood, Senior Product Management Director, Risk

STIR/SHAKEN provides inbound contact centers with an additional data element to establish trust in callers: the phone number’s attestation level. Attestations provide a helpful signal for identifying good callers and determining treatment logic, but they do not substitute for an inbound caller authentication solution.
