Yeastar MyPBX GSM 1 Channel Module Central Wireless Expansion Infrastructure SlotÂ
The Yeastar MyPBX GSM 1 Channel Module is an enterprise-grade, field-installable hardware expansion component engineered to introduce a native cellular voice trunk directly into compatible Yeastar IP-PBX phone systems. Purpose-built to eliminate reliance on external copper landlines or standalone gateway boxes, this low-profile circuit card mounts internally onto the main telephone exchange board. Whether you are adding a mobile network escape route for corporate offices in Westlands, securing real-time client communications for a financial hub in the Nairobi CBD, or deploying localized mobile connectivity in Kilimani, this robust module ensures continuous telecom cost control and hardware-level uptime.
Direct Cellular Voice Routing and Multi-Band Network Interoperability
Integrating the Yeastar GSM module into your communications exchange is an exceptionally effective method to bypass regional fixed-line outages and eliminate expensive landline-to-mobile toll charges.Â

Why Deploy the Yeastar MyPBX GSM Module
The Yeastar GSM module delivers the precise combination of immediate capital expense reduction, robust backup voice infrastructure, and automated system text messaging capabilities required for active workplaces.Â
1 Strategic Telecom Cost Minimization and LCR Pairing
Drastically reduce your monthly corporate airtime bills. By placing a local carrier SIM card directly into your exchange, the PBX can leverage an intelligent Least Cost Routing (LCR) dial plan. When an executive dials a mobile number, the system automatically patches the session out through this GSM module, transforming pricey interconnected landline-to-mobile charges into low-cost, on-network mobile-to-mobile rates.
2 High-Reliability Mobile Trunk Backup and Business Uptime
Protect your business from sudden physical data line breaks or localized internet outages. Acting as a critical wireless failover trunk, the module ensures that if your primary fiber connections go dark, your essential client hotlines, sales queues, and emergency communication channels are automatically rerouted through the cellular network to keep your workflow fully operational.
3 Web-Based Corporate Short Message Service (SMS) IntegrationÂ
Move past basic voice workflows by leveraging your system’s underlying messaging potential. Once the SIM card is activated, administrators and team members can harness the IP-PBX software interface to send and receive text messages, dispatch automated customer notifications, manage visual appointment reminders, or accept text replies directly through a centralized computer console.
