Скачать или смотреть Media gateway

A media gateway is a translation device or service that converts media streams between disparate telecommunications technologies such as POTS, SS7, Next Generation Networks or private branch exchange systems. Media gateways enable multimedia communications across packet networks using transport protocols such as Asynchronous Transfer Mode and Internet Protocol.
Because the media gateway connects different types of networks, one of its main functions is to convert between different transmission and coding techniques. Media streaming functions such as echo cancellation, DTMF, and tone sender are also located in the media gateway.
