Plano, TX –Ribbon Communications Inc. (Nasdaq: RBBN), a global provider of real time communications software and IP Optical networking solutions to service providers, enterprises, and critical infrastructure sectors, today announced that Intrado, a global leader in technology-enabled services, has chosen Ribbon Call Trust™ for STIR/SHAKEN compliance.
