Yeastar EX08 Yeastar Yeastar S-Series PBX Expansion Card

The Yeastar EX08 is an interface expansion module designed to extend the port capacity of Yeastar S-Series IP PBX systems. This module provides eight additional expansion slots that can accommodate various telephony interface cards, including FXS, FXO, and BRI modules, allowing businesses to scale their telephony infrastructure as requirements grow.

The EX08 is specifically engineered for use with Yeastar S100 and S300 PBX platforms, enabling organisations to increase their analogue trunk connections, analogue extension ports, or ISDN BRI lines beyond the base unit’s built-in capacity. This modular approach provides flexibility in deployment, allowing administrators to configure the precise mix of interfaces required for their environment.

As part of Yeastar’s established S-Series ecosystem, the EX08 offers a cost-effective method of expanding telephony capacity without replacing the core PBX hardware. It is well-suited to organisations transitioning from legacy PSTN infrastructure or those requiring additional analogue endpoints such as fax machines, door entry systems, or analogue handsets.
