First Orion Introduces SIP Redirect Call Authentication Integration to Expand Access to Trusted, Logo Branded Calling

First Orion, a leading provider of branded communications solutions, today introduced a new patented SIP redirect-based, end-to-end call authentication integration method. This innovation enables enterprises to more easily and securely authenticate outbound calls while delivering trusted calls at scale. The technology behind INFORM® with Logo and SENTRY® Call Blocking is now accessible through this new integration, allowing businesses to verify that calls are valid as they reach carrier networks. Only authenticated calls are branded with INFORM, while unauthenticated calls can be blocked using SENTRY.

The SIP redirect approach simplifies the authentication process by integrating directly with existing enterprise telephony infrastructure. This reduces the complexity and cost traditionally associated with call authentication, making it more feasible for a broader range of businesses to adopt trusted calling. By leveraging the SIP protocol, First Orion ensures compatibility with most modern phone systems without requiring extensive hardware upgrades.

Call authentication has become increasingly important as robocalls and phone scams erode consumer trust. According to the Federal Communications Commission, Americans received an estimated 4 billion robocalls per month in 2025. Brands that authenticate their calls can display their logo and name, helping consumers answer with confidence. First Orion's solution not only enhances security but also improves customer engagement rates.

“With this new integration, we are democratizing access to call authentication,” said a spokesperson for First Orion. “Enterprises of all sizes can now protect their brand reputation and build trust with their customers.” The company has been at the forefront of branded communications, working with Fortune 500 companies and integrating into the largest U.S. mobile carriers.

The announcement underscores the growing demand for secure communication channels. As businesses increasingly rely on phone outreach for customer service, fraud prevention, and marketing, the ability to authenticate calls becomes a competitive advantage. First Orion's SIP redirect method represents a significant step forward in making branded calling accessible and scalable.
