Yeastar S2 Module – 2 FXS Ports

Description

The Yeastar S2 Module is a telephony expansion module designed for compatible Yeastar S-Series VoIP PBX and selected Yeastar P-Series PBX systems. It adds 2 FXS ports to the PBX, allowing businesses to connect analog telephones or fax machines directly to the system without needing a separate external gateway.

This module is ideal for organizations that still use analog phones, fax devices, or legacy analog endpoints but want to keep them integrated within a modern IP PBX environment. Once installed inside the PBX chassis, the S2 module activates 2 RJ11 FXS interfaces on the front panel of the PBX, giving a simple and space-saving way to expand analog extension capacity.

The Yeastar S2 is commonly used in offices, clinics, hotels, retail stores, and small business telephony systems where a mix of IP and analog endpoints is still required. It helps businesses preserve existing analog devices while benefiting from the management and communication features of a Yeastar PBX system.

Technically, the module provides 2 FXS ports and supports analog endpoint connection over standard RJ11 interfaces. It is built for use with supported Yeastar PBX appliances such as S20, S50, S100, S300, S412, and selected P-Series PBX models depending on the chassis and expansion board support. The module is installed internally into the PBX module slot or compatible expansion board, making it part of the PBX hardware rather than a standalone device.

Overall, the Yeastar S2 Module is a practical solution for adding 2 analog extension ports to a Yeastar PBX, helping businesses integrate traditional analog devices into a SIP-based communication system in a clean and cost-effective way.
