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, made on April 30, 2026, expands access to the company's INFORM® with Logo and SENTRY® Call Blocking technologies.
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. By leveraging a SIP redirect approach, the integration simplifies the authentication process for enterprises, reducing the complexity and cost typically associated with implementing call authentication solutions.
The new method is designed to address the growing problem of spam and fraudulent calls, which erode consumer trust and damage brand reputation. With this integration, enterprises can ensure that their legitimate calls are displayed with a branded logo and verified caller information, while suspicious or unauthorized calls are blocked before reaching consumers. This not only improves answer rates for businesses but also enhances security and transparency for end users.
First Orion's SIP redirect-based authentication works by intercepting outbound call requests at the enterprise level and redirecting them through First Orion's secure authentication platform. The platform validates the call's origin and authenticity before passing it to the carrier network, where it can be branded or blocked accordingly. This approach eliminates the need for enterprises to modify their existing telephony infrastructure or deploy complex software, making it accessible to a wider range of businesses.
The integration is particularly significant for industries that rely heavily on outbound calling, such as financial services, healthcare, and customer support. For example, banks can authenticate calls to customers about suspicious transactions, ensuring that the call is trusted and reducing the risk of phishing attacks. Similarly, healthcare providers can use branded calling to confirm appointment reminders or deliver test results, improving patient engagement and trust.
First Orion's announcement comes as regulators and carriers intensify efforts to combat illegal robocalls and caller ID spoofing. The STIR/SHAKEN framework has established a baseline for call authentication, but many enterprises still struggle to implement it effectively. First Orion's new SIP redirect method offers a more streamlined path to compliance while delivering additional benefits like branded calling.
