American technology companies Ribbon Communications and Neustar have announced an expansion of their cooperation to provide a comprehensive solution designed to tackle the issues of robocalling and call spoofing. Ribbon, a global software leader providing IP-based real-time communications security and software solutions, is working in partnership with Neustar, the exclusive host of the ATIS Robocalling Testbed, to develop and support an integrated platform for their STIR-SHAKEN implementation.


Secure Telephone Identity Revisited (STIR) standards and the Signature-based Handling of Asserted information using toKENs (SHAKEN) framework were developed by the IETF and ATIS/SIP Forum NNI Task Force, respectively. STIR-SHAKEN is a major industry initiative set up to help service providers protect consumers against illegal robocalls and caller ID spoofing.


The Ribbon session border controller, as well as policy and routing products coupled with the Neustar Certified Caller platform will enable service providers to promptly detect suspicious calls and inform business and consumer customers of potential illegal robocalls and spoofed calls. The end-users will have the option to either answer or ignore the calls. At the moment, the end-user does not receive any indication regarding the reliability or authenticity of the call.


Kevin Riley, Chief technology officer at Ribbon, said, “Nearly half of all calls to mobile phones in the U.S. in 2019 will be scam or robocalls and our joint efforts with Neustar are designed to help our service provider customers address this growing epidemic head-on. Our SBC and policy and routing solutions combined with Neustar’s call authentication and identity protection capabilities will deliver our customers a best-in-class solution to mitigate robocalling and call-spoofing.”


“Ribbon and Neustar are working closely together to deliver a holistic and seamless STIR-SHAKEN solution that will help our service provider customers better serve the end-user by distinguishing legitimate calls from illegal robocalls,” said James Garvert, Vice president and General manager, Caller Identification Solutions, Neustar. “We are passionately committed to working together to help the industry quickly adopt the STIR-SHAKEN standards, which will ultimately result in higher customer satisfaction and trust, by blocking nuisance calls before they reach subscribers.”
