Yeastar Expansion Module GSM

The Yeastar GSM Module is a versatile expansion component designed to add mobile cellular connectivity to your Yeastar S-Series or P-Series PBX. By inserting a local SIM card into this module, you enable your office phone system to make and receive calls directly over the GSM network. This is an essential hardware upgrade for businesses looking to reduce mobile-to-mobile calling costs, provide a reliable backup for landlines, or establish a professional presence in areas without traditional underground cabling.

Configure your PBX to automatically route outgoing calls to mobile numbers through the GSM module, taking advantage of low-cost “on-net” mobile rates.

Acts as a critical “voice backup.” If your primary SIP trunk or fiber internet goes down, your business can remain reachable via the GSM mobile number.

Supports quad-band GSM frequencies, ensuring it works seamlessly with all major Ghanaian providers including MTN, Telecel (Vodafone), and AirtelTigo.
