Yeastar GSM modulee Yeastar Yeastar S-Series PBX Module

The Yeastar GSM Module is a mainline expansion module designed to add GSM cellular connectivity to compatible Yeastar IP PBX systems. This module enables organisations to route calls over mobile networks, providing an alternative trunk line or serving as a backup when traditional PSTN or SIP trunking is unavailable.

Deployed within Yeastar S-Series or other compatible PBX platforms, the GSM module allows businesses to leverage mobile network coverage for outbound and inbound calling. This is particularly useful for sites with limited fixed-line infrastructure, or where mobile call routing offers cost advantages for certain destinations.

GSM modules remain relevant for organisations requiring hybrid telephony solutions that combine VoIP with cellular connectivity. The module slots directly into the Yeastar PBX chassis, integrating seamlessly with the system’s call routing and management features.
