Yeastar EX08 Expansion Card (EX08)

The Yeastar EX08 Expansion Card is a modular expansion board designed to extend the physical telephony interface capacity of compatible Yeastar S-Series and P-Series VoIP PBX systems. Built for flexibility and scalability, the EX08 allows businesses to integrate analog, digital, and cellular communication technologies into a single PBX platform, making it ideal for organizations that need to adapt their phone system as requirements evolve.

Product Features

Modular Expansion Architecture

The Yeastar EX08 features four onboard module slots that support a wide range of Yeastar telephony modules. This modular design allows businesses to customize their PBX configuration based on current needs while remaining ready for future expansion.

Multiple RJ11 Interfaces

With eight external RJ11 ports, the EX08 provides ample connectivity for analog devices and lines. These ports support various telephony modules, enabling flexible deployment of FXS, FXO, and other interfaces.

Broad Module Compatibility

The expansion card supports multiple Yeastar modules, including S2, O2, SO, B2, and GSM, 3G, or 4G cellular modules. This compatibility allows organizations to combine analog phones, PSTN lines, ISDN BRI, and mobile networks within one unified PBX system.

Seamless Integration with Yeastar PBX Systems

Designed specifically for Yeastar platforms, the EX08 integrates smoothly with Yeastar S100, S300, P560, and P570 PBX systems. The card installs directly into the PBX motherboard, ensuring reliable performance and system stability.

Scalable System Growth

Depending on the PBX model, multiple EX08 expansion cards can be installed to significantly increase interface capacity. This enables businesses to scale their communication infrastructure without replacing their existing PBX hardware.

Hot-Swappable and Easy to Manage

In supported systems, modules can be hot-swapped, allowing upgrades or changes without powering down the PBX. All ports and modules are managed through the Yeastar PBX web interface, simplifying configuration, monitoring, and diagnostics.
