A GSM (Global System for Mobile Communications) gateway is a proven device that enables users to make and receive calls from a fixed handset as though it was a mobile phone. By switching every Fixed Line to Mobile (F2M) call to Mobile to Mobile (M2M), users can reduce their communication costs by 40.80 per cent. A GSM gateway (also known as a Fixed Cellular Terminal) is a device which is connected to one or more GSM SIM (Subscriber Identity Module) card(s). Once installed the GSM gateway will intercept all calls made from the fixed handset(s). Using intelligent programming and least cost routing (LCR), the gateway will determine if the call is being made to a mobile phone.
