VoIP GSM gateway (GoIP gateway) is a device that can reduce the cost of calling mobile networks from fixed telephone lines. It can route directly between IP, digital, analog, and mobile networks. GoIP gateways are increasingly being used by telephone operators to connect IP calls to mobile networks. In areas where fixed line services are unavailable or much more expensive than mobile costs, GoIP gateways are an irreplaceable alternative.
