REDCOM demonstrates effectiveness of STIR/SHAKEN caller authentication standards with the ATIS Robocalling Testbed

May 30, 2019

REDCOM Laboratories, Inc., the leading provider of solutions for the network service layer, announced today it has successfully completed interoperability testing with the ATIS Robocalling Testbed that demonstrates the interoperability of the company’s STIR/SHAKEN implementation within the REDCOM Personalized Call Screening software. These tests are part of a broader industry effort to help service providers protect consumers against unwanted robocalls and caller ID spoofing.

“Nuisance calls are one of the biggest pain points affecting consumers today. The U.S. government has made it clear that solving this problem is a top priority this year,” said Shannon Chevier, Director of Product Management for REDCOM. “Our Personalized Call Screening solution will allow service providers to offer consumers real protection against the onslaught of robocalls. Service providers that implement REDCOM software not only get a proven STIR/SHAKEN solution, but also a ‘best of all worlds’ toolkit that includes reputation scoring, white and blacklists, and audio CAPTCHAs.”

The virtualized testing facility, hosted by the Neustar Trust Lab, supports a joint effort from the Internet Engineering Task Force (IETF) and the Alliance for Telecommunications Industry Solutions (ATIS) called STIR/SHAKEN, which gives service providers the ability to authenticate, digitally sign, and verify calling party numbers. This testing confirms REDCOM’s successful implementation of both the Secure Telephone Identity Revisited (STIR) standard and the Signature-based Handling of Asserted information using toKENs (SHAKEN) framework.

“Neustar is committed to supporting the industry in combating illegal robocalling and call-spoofing,” said James Garvert, Communications Solutions General Manager for Neustar. “One of our efforts in support of this commitment, since early 2017, is hosting and operating the ATIS Robocalling Testbed and supporting participants, such as REDCOM, with their STIR/SHAKEN interoperability testing.”
