About Avaya media servers and gateways
Issue 6 February 2007 21
Note:
Note: Some of Avaya’s media servers and gateways were tested against extreme
physical and environmental requirements such as shock, vibration, and EMI.
These tests were performed by the United States Navy for media server and
gateway use on their ships. The Navy uses specialized racks and reinforcements
although no physical changes have been made to the servers and gateways
themselves. Customers that are interested in obtaining information for the design
and implementation of such a ruggedized solution can contact the Avaya Custom
Engineering Group.
Media servers
Avaya’s line of media servers provides a robust application platform based on industry-standard
operating systems. This platform supports distributed IP networking and centralized call
processing across multiprotocol networks. These servers are available as an integrated solution
with other servers or can operate independently.
Avaya media servers have the following features and benefits:
● Redundant, survivable call processing and media processing supports crucial business
continuity.
● Standards-based computing supports Linux, Microsoft Windows, and the Avaya

operating system.
● Distributed survivable IP networking supports campus, global-multisite, and branch
environments.
Media gateways
Avaya media gateways connect to an Avaya media server, either directly or indirectly through
other media gateways. Media Gateways are the stackable and modular hardware elements of
your communication system, and they deliver connectivity to a variety of endpoint and trunk
types – allowing data, voice, FAX, video, and messaging capabilities on your network. The
connections between media gateways that allow the passage of these media types is called the
"bearer network." The connections between the media server and the media gateways for call
control signaling is called the "control network."
Avaya media gateways support both bearer and signaling traffic that is routed between packet-
and circuit-switched networks. Avaya media gateways provide a variety of flexible deployment
options. These options include 100% Internet Protocol (IP) environments and blended
environments such as IP and Time Division Multiplexing (TDM).
