Yeastar SO Module Overview

This module simply allows you to terminate 1 analog extension with an analog telephone line as a back-up and failover for power outages, etc. This card can be used directly with the S412, S20 and S50 Yeastar S-Series models. To use this module with the S100 and S300, you will require 1 or more EX08 expansion cards.


These expansion modules are "push pin" snap in type expansion boards which are easy to install by most users. Simply unplug your PBX System for electrical safety before installing, remove the cover and pop in the card into the compatible slot on your phone system model, or the EX08/expansion cards to begin using once installed.
