Robocalling Testbed

The ATIS Robocalling Testbed, hosted by the Neustar Trust Lab, serves as the industry interoperability test facility to validate the effectiveness of caller authentication standards developed by the Internet Engineering Task Force (IETF) and ATIS. Specifically, ATIS developed "Signature-based Handling of Asserted information using toKENs" (SHAKEN) as an implementation framework for service providers to better combat robocalls and call spoofing on IP-based networks.

Any service provider with an assigned Operating Company Number (OCN), as maintained by the National Exchange Carrier Association, Inc. (NECA), is eligible to participate. Other parties, such as equipment manufacturers, may participate if they have solutions relevant to the SHAKEN framework available to test.

All Robocalling Testbeds participants have signed the ATIS Testbeds NDA. View all signatories here.
