Media Gateway Overview
The Media Gateway is a family of components, which can deliver data, voice, fax, and messaging
capabilities over an IP network. It is a VoIP system that acts as an IP PBX and messaging server
and a VoIP gateway. In addition, it performs the function of a gatekeeper and an IP media
management resource for tone detection and generation, conferencing, and call classification.
The Media Gateway components are controlled through the Media Gateway Processor (MGP).
The MGP detects when a media module is inserted or removed and transfers information from
the VoIP engine to the other components.
The Avaya G250/G350/G450’s Media Gateway converges the power of Avaya Call Processing
(ACP) software with the power of distributed switching from the Avaya G250/G350/G450
Device. It provides IP PBX functionality using open standards and an open operating system.
The device connects to ACP using either an internal or external call controller. The ACP serves
as the Avaya G250/G350/G450 Device’s gatekeeper.
