YEASTAR O2 MODULE

The Yeastar O2 Module is a 2-port FXO expansion module designed to add analog PSTN (Public Switched Telephone Network) connectivity to compatible Yeastar S-Series and P-Series IP PBX systems. It enables businesses to connect up to two analog telephone lines directly to their IP PBX, allowing seamless integration between traditional telephone networks and modern VoIP communications. This module is an ideal solution for organizations that need to retain existing PSTN lines while benefiting from the advanced features of an IP-based phone system.

The O2 Module installs directly into a compatible Yeastar PBX, providing two RJ11 FXO ports that support inbound and outbound calls over analog telephone lines. It features built-in echo cancellation, reliable ring voltage detection, and support for multiple signaling modes to ensure stable, high-quality voice communication. Its modular design allows businesses to expand their telephony infrastructure as communication requirements grow without replacing the entire PBX system.

Compatible with a range of Yeastar S-Series models such as S20, S50, S100, S300, and S412, as well as selected P-Series systems including P550, P560, and P570, the O2 Module offers a cost-effective way to integrate legacy analog lines into a unified communications platform. It is ideal for businesses, hotels, retail stores, healthcare facilities, and organizations transitioning from traditional telephony to VoIP while maintaining existing PSTN connectivity.
