Yeastar GSM Module (Single Slot) with Antenna | PBX-GSM

The Yeastar GSM Module (YST-GSM) is an expansion card that adds a single GSM channel to a compatible Yeastar IP PBX system. It allows your business to use a standard mobile SIM card as a trunk for making and receiving calls and sending SMS messages directly through your PABX. This module offers a cost-effective alternative to fixed-line trunks and can function as a reliable backup communication line. The single SIM port module supports quad-band GSM (850/900/1800/1900MHz) and is designed for use with Yeastar S-Series VoIP PBX and P-Series PBX Systems (requires an expansion board). Installation is simple, providing direct integration into your telephony infrastructure.
