A GSM Gateway is a device that connects GSM mobile networks with VoIP or traditional telephony systems. In simple terms, it allows businesses to route calls between mobile networks and IP-based systems, helping reduce call costs and improve connectivity.
It is widely used in offices, call centers, and multi-branch businesses where mobile call traffic is high.
How Does a GSM Gateway Work?
A GSM Gateway works by inserting SIM cards into the device. When a call is made from an IP PBX or VoIP system, the gateway routes the call through the SIM card over the GSM network instead of a traditional phone line.
Converts VoIP calls into GSM calls
Uses SIM cards to connect with mobile networks
Routes incoming GSM calls to IP PBX or SIP systems
Supports two-way communication (VoIP ↔ GSM)
This helps businesses take advantage of lower mobile call rates.
