## Long description

The Yeastar GSM module 1\*GSM trunk is an add-on telephony module designed to provide a single GSM trunk interface for compatible Yeastar PBX systems. It enables routing of voice calls over GSM networks and allows SIM-based connectivity to mobile operators. The module integrates with existing VoIP infrastructures to offer mobile network backup, local GSM call termination and simplified connectivity for environments where landlines are limited or unavailable.
Advantages
The module delivers a straightforward way to add GSM connectivity to a Yeastar PBX without altering the existing SIP infrastructure. It supports seamless routing between VoIP and mobile networks, reduces call costs for local GSM termination, and provides redundancy for outgoing and incoming calls when fixed-line service is interrupted. Compact in size and focused on a single trunk, the module requires minimal configuration and fits into small office or remote site deployments.
Suitable for
 Small offices needing mobile network backup for voice calls
 Remote sites without reliable landline service
 Scenarios requiring local GSM call termination to reduce costs
 Temporary installations or pop-up sites where quick SIM-based connectivity is required
Key specifications
 Interface: single GSM trunk slot compatible with Yeastar PBX modules
 Connectivity: SIM-based GSM network access for voice calls
 Integration: interoperable with SIP/VoIP routing on supported Yeastar systems
 Form factor: compact add-on module designed for rack or chassis integration with the PBX
 Power and signaling: uses the PBX power and control interfaces for management
How to use
Install the module into the compatible Yeastar PBX expansion slot according to the PBX installation instructions, insert an activated SIM card, and configure GSM trunk settings in the PBX web interface. Define inbound and outbound routing rules to control how calls are directed between SIP extensions and the GSM trunk. Adjust codec, caller ID presentation, and GSM-specific settings as needed to match operator requirements and call quality preferences.
Usage recommendations
Use an active SIM card with the appropriate voice plan for your expected call volumes, and verify GSM signal strength at the installation site. Configure failover rules so the GSM trunk activates automatically when primary PSTN or SIP routes are unavailable. Monitor usage and call quality through the PBX management interface and keep firmware of both PBX and module up to date for compatibility and security.
