Yeastar GSM M-35 S-Series PBX Card / Module Image 1

Yeastar GSM M-35 module for adding GSM connectivity to Yeastar S-Series PBX systems.

The Yeastar GSM M-35 is a GSM expansion module designed to add mobile network connectivity to compatible Yeastar IP PBX systems. This module enables businesses to make and receive calls over GSM networks, providing an alternative trunk option alongside traditional SIP and PSTN connections.

The M-35 module is intended for installation in Yeastar S-Series PBX systems, allowing organisations to reduce mobile call costs by routing calls through the GSM network directly from the PBX. This is particularly useful for businesses with high volumes of calls to mobile numbers or those requiring mobile network backup for business continuity.

The module supports a single GSM channel and integrates seamlessly with Yeastar’s unified communications platform. It is well-suited for small to medium-sized businesses looking to optimise their telephony costs and maintain flexible connectivity options.
