Yeastar Fxo2 Module

The Yeastar FXO2 (O2) Module is an expansion telephony interface for Yeastar IP PBX systems that adds two FXO (Foreign Exchange Office) ports to your PBX, allowing you to connect traditional analog PSTN (Public Switched Telephone Network) phone lines directly to the system. It’s designed to expand call routing options, enable PSTN line connectivity and failover, and integrate legacy telephone infrastructure with modern VoIP setups. This modular card fits into compatible Yeastar S-Series and P-Series PBX chassis, providing a scalable and flexible way to bridge analog lines with your VoIP communication platform.
