Yeasta Ex08 PBX Expansion Module

The Yeastar EX08 is a modular expansion card used with compatible Yeastar S-Series IP PBX systems. It adds eight additional telephony ports to the PBX, allowing the system to support more analog lines, phones, or other interface types depending on the modules installed. The board has multiple slots for flexible configuration, enabling businesses to expand their phone system capacity without replacing the main PBX. It’s ideal for growing offices that need more connectivity options for traditional phone lines or devices alongside their VoIP infrastructure.
