PLANO, Texas, Sept. 20, 2022 /PRNewswire/ -- 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 Paritel, a France-based provider of telecom solutions to enterprises and small businesses, has selected Ribbon's STIR/SHAKEN solution to ensure its compliance with the "Loi Naegelen," (Naegelen Law) requiring French service providers to implement a solution protecting their customers from various types of telephony based fraud by July 2023.

"Malicious calls from bad actors are causing our customers to lose trust in the phone network," said Guillaume Rouderges, Telecom Infrastructure Manager, Paritel. "We're pleased to partner with Ribbon to help restore integrity to our customers' calling experience, in addition to meeting the requirements of the Loi Naegelen.
