Understanding Yeastar Expansion Cards

As businesses grow, communication needs change. Adding more phone lines, connecting mobile networks, or expanding extensions should not require replacing your entire PBX system. This is where Yeastar Expansion Cards come in. At Hubtech Online Shop, we help businesses upgrade their communication systems efficiently using genuine Yeastar solutions.

What Is a Yeastar Expansion Card

A Yeastar Expansion Card is a hardware module installed in a Yeastar IP PBX system to increase capacity and functionality. These cards let businesses add connections such as analog lines, extensions, GSM channels, or digital trunks without replacing the main PBX unit. Yeastar expansion cards enable your PBX to grow with your business.

How Yeastar Expansion Cards Work

Yeastar PBX systems are designed with expansion slots. When business requirements increase, an expansion card is inserted into the available slot, instantly adding new communication capabilities. Once installed, the system recognizes the card and allows configuration through the Yeastar management interface.

Types of Yeastar Expansion Cards

• FXO Expansion Cards: These link your PBX system to local PSTN landlines, allowing inbound and outbound calls through external telecom providers, and giving your business a reliable telephone connection.
