What is a Gateway?
A gateway is point on a network that acts as an entrance to another network. For example, if you have an internet connection at home you will have a gateway that acts as the junction between your home network and the internet which makes sure your data packets are sent and received (routed) correctly. A media gateway, often referred to a gateway or VoIP Gateway, within the world of VoIP communications, is similar in purpose but different in that it is a translation device or service that converts digital media streams.
