Legos Selects Ribbon to Implement STIR/SHAKEN Solution to Safeguard Customers Against Telephony Fraud and Comply with French Regulation

Plano, TX, 4 May 2023 – Ribbon Communications Inc. (Nasdaq: RBBN), a global provider of real time communications technology and IP optical networking solutions to many of the world’s largest service providers, enterprises, and critical infrastructure operators to modernize and protect their networks, today announced that European fixed and mobile telephony operator Legos (Local Exchange Global Operations Services), has selected Ribbon’s STIR/SHAKEN solution, to ensure compliance with the MAN (Mécanisme d'Authentification des Numéros) Project conducted by the regulator ARCEP. Through this deployment, Legos customers are expected to benefit from increased call trust and a drastic reduction in malicious calls, helping to safeguard them against telephony-based fraud.

“With malicious calls from bad actors on the rise we want to help build assurances for our customers and protect network users against robocalls, fraud and call spoofing,” said Michel Gacem, CTO & Solution Manager Director, Legos. “We’re excited to be furthering our existing partnership with Ribbon, whose expertise in this field will enhance the security of our network services.”

Part of the Ribbon Call Trust® portfolio, Ribbon’s STIR/SHAKEN solution is designed to meet requirements for caller identity authentication, signing, verification and certificate management as defined by French law. Legos will leverage Ribbon’s expertise through similar implementations in the USA that have well proven benefits to customers. In addition to STIR/SHAKEN, Legos will add Ribbon’s market leading core SBC for security and interworking, and PSX, which delivers session control for VoIP services on SBCs, media gateways and call controllers.

“We’re pleased to be extending our longstanding partnership with Legos, supporting the business with full compliance with impending French regulation,” said Ribbon’s Christine Bouhiron, Head of Sales and Country Manager, France. “Our STIR/SHAKEN solution was created to help our customers adapt to the regulatory landscape across the USA and Europe. Our leadership and experience in identity assurance will enable Legos to improve the overall telephony experience for its users.”
