Media Gateway (Transcoder) - Real-Time Communication on AWS

Media Gateway (Transcoder)

A typical voice solution allows various types of CODECs. Some of the common CODECs are G.711 µ-law for North America, G.711 A-law for outside of North America, G.729, and G.722. When two devices that are using two different CODECs communicate with each other, a media server translates the CODEC flow between the devices. In other words, a media gateway processes media and ensures that the end devices are able to communicate with each other.
