Yeastar Expansion Module O2

The Yeastar O2 Module is a high-performance expansion component designed to add analog telephone line (PSTN) connectivity to your Yeastar S-Series or P-Series PBX. Featuring two FXO (Foreign Exchange Office) ports, the O2 module allows your modern VoIP system to interface directly with traditional copper landlines from your local service provider. This is an essential hardware upgrade for businesses that want to maintain their existing, well-known business numbers while enjoying the advanced features and flexibility of an IP-based communication system.

Each O2 module provides two RJ11 ports, allowing you to connect up to two physical analog phone lines (PSTN trunks) to your PBX.

Features built-in line echo cancellation (LEC) to ensure that analog-to-digital voice conversion remains clear and free of the “tunnel” sound often associated with older lines.

Fully programmable to match the electrical standards of telecommunications providers worldwide, including all major carriers in Ghana.
