The gateway also may translate between audio, video, and data formats, and may perform signaling conversions between the H.225 packet protocol and external protocols such as SS7 and Q.931. Alternatively, signaling conversions may be performed by gatekeepers, call processors, or session border controllers.

The router or communication node connecting an internal or local area network to the Internet or another type of wide-area network. Today, the term has taken on a slightly wider definition in which a gateway is dedicated to a specific functional service to provide an intermediary between two or more systems. For example, an LDAP master server (a server that provides authentication and directory services) in a multimode master setup is a gateway when more than one master server exists. Gateway is also the name of a successful computer and peripherals vendor operating mainly through online channels.
