First Orion, a leading provider of branded communications solutions, today introduced a new patented SIP redirect-based, end-to-end call authentication integration method, enabling enterprises to more easily and securely authenticate outbound calls while delivering trusted calls at scale. The announcement marks a significant advancement in call authentication technology, expanding access to features like INFORM® with Logo and SENTRY® Call Blocking.
Call Authentication, the technology that delivers INFORM with Logo and SENTRY Call Blocking, is now available through this new Call Authentication integration. This capability enables enterprises to verify that calls are valid as they reach carrier networks, branding only authenticated calls with INFORM or blocking unauthenticated calls with SENTRY. The SIP redirect approach simplifies the integration process, reducing complexity for enterprises seeking to protect their customers from fraud and enhance brand trust.
By leveraging SIP redirect, First Orion’s solution allows enterprises to authenticate calls without requiring extensive changes to their existing infrastructure. This method ensures that calls are verified at the network level, providing a seamless experience for both businesses and consumers. The technology is designed to work with the largest U.S. mobile carriers, making it accessible to a wide range of enterprises.
First Orion’s comprehensive suite of branded communications solutions aims to improve customer engagement, enhance security and transparency, and provide actionable insights. In addition to branded calling and messaging, the company offers advanced analytics to optimize call programs and real-time fraud detection to protect customers. These innovations enable enterprises to provide trust and transparency at scale, a critical need in an era of rampant phone scams and spam calls.
The introduction of this new integration method is particularly important as businesses seek to rebuild consumer trust in phone communications. With the rise of robocalls and spoofing, consumers are increasingly wary of answering unknown calls. By branding authenticated calls with logos and blocking unauthenticated ones, First Orion helps enterprises ensure that their legitimate calls are answered, while protecting customers from fraudulent activity.
First Orion is a valued partner to Fortune 500 companies and is integrated into the largest U.S. mobile carriers. The company’s solutions are designed to address the growing demand for secure and transparent communications. For more information, visit firstorion.com.
