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.
