P-Series PBX Firmware Update: STIR/SHAKEN Support and Red Hat SSO Integration

P-Series PBX Enhances Security and Functionality

The latest P-Series PBX firmware update introduces powerful new features aimed at improving security, regulatory compliance, and user convenience. With the addition of built-in STIR/SHAKEN protocol support, Red Hat Single Sign-On (SSO) integration, and enhanced management tools, businesses now have access to a more robust and streamlined communication system. These updates empower telecom providers and enterprises to stay ahead of industry demands and regulatory requirements while enhancing user satisfaction. Let’s delve deeper into the key updates and their benefits.

STIR/SHAKEN: Combatting Caller ID Spoofing

One of the most exciting developments in this update is the inclusion of built-in STIR/SHAKEN protocol support for the P-Series PBX Cloud Edition. This set of protocols, mandated by the FCC in the U.S. and the CRTC in Canada since 2021, combats caller ID spoofing, a growing issue in the telecom industry. By integrating this framework directly into the PBX, businesses can now authenticate and verify calls without the need for complex external solutions. This not only reduces spoofed calls, fraud, and robocalls but also boosts customer trust by ensuring reliable and authenticated communication.

For partners, implementing STIR/SHAKEN does require obtaining an STI certificate from the policy administrator. Yeastar provides detailed guidance to streamline this process, ensuring ease of implementation. The feature is now live for P-Series Cloud Edition Hosted deployments and will roll out for BYOI users on November 17, 2025. This seamless integration reaffirms Yeastar’s commitment to delivering compliance-ready solutions that simplify user experience while adhering to global telecom regulations.

Red Hat SSO Integration: Simplified User Management

The update also introduces support for Red Hat Single Sign-On (SSO), enhancing security and easing system administration. Red Hat SSO is a widely-used solution that enables users to access multiple platforms with a single set of login credentials while allowing centralized control for administrators. Built on the SAML 2.0 protocol, this integration positions the P-Series PBX as the Service Provider (SP) and Red Hat as the Identity Provider (IdP), providing a seamless and secure authentication process.

This feature automates user account management, thereby eliminating manual tasks and reducing errors. Not only does this improve security, but it also offers users a smooth one-click login experience across systems. Enterprises using Red Hat environments can now benefit from a unified and efficient login mechanism, reducing complexities in managing user credentials.

Improved DOD Management and SIP 302 Redirect Support

Another improvement focuses on enhancing flexibility with direct outward dialing (DOD) selection and monitoring. Users can now select outbound numbers with feature codes directly from their phone interface or the Linkus UC Clients panel, a valuable tool for businesses handling diverse client bases. Administrators, on the other hand, can monitor DOD switching via BLF (Busy Lamp Field) for better visibility and control over trunk usage. This level of accessibility improves efficiency in managing business communication.

Additionally, P-Series PBX now supports SIP 302 Redirect to comply with French regulations, enabling the preservation of the original caller ID when forwarding calls to external numbers. This ensures transparency and provides recipients with accurate caller information, enhancing overall clarity and compliance in communications.
