A GSM Gateway (also called a SIM Gateway or GSM VoIP Gateway) is a hardware device that connects a traditional telephony system or VoIP system to GSM mobile networks. It essentially allows voice communication between GSM networks and IP-based networks (like a PBX system), letting you make and receive calls via mobile SIM cards directly from your office phone system or softphone.
Think of it as a bridge between cellular networks and your business communication tools.
How Does It Work?
A GSM Gateway contains one or more SIM card slots, and each slot connects to the GSM network just like your phone does. When paired with a VoIP or PBX system, the gateway uses SIP protocols to transmit voice data over IP while routing calls through GSM.
For example, if you have a 2 Port GSM Gateway, you can use two SIM cards and run two simultaneous GSM calls. With higher-end models like an 8 Port or 32 Port GSM Gateway, you can manage multiple concurrent calls, which is ideal for businesses with large call volumes.
