Administering Avaya Video Conferencing Solution 6.0.1 Issue 2.1 April 15, 2011 9
Chapter 1: Avaya Video Conferencing Solution
The Avaya Video Conferencing Solution (AVCS) enhances and extends the use of Avaya
Aura™ Communication Manager, Avaya Aura™ Session Manager, and Avaya Aura™ System
Manager as a SIP-based platform for video communications. Communication Manager,
Release 6.0.x, is an H.323-to-SIP and a SIP-to-SIP video signaling gateway that supports
single and mixed protocol video deployments.
The key video components of AVCS are:
● Gatekeepers provide call admission control and bandwidth management for all SIP and
H.323 video calls and video telephony features. Communication Manager and Session
Manager serve that role within AVCS. The Polycom CMA is supported only in a
neighbored gatekeeper configuration that uses CMA to provide the H.323 call control for
all H.323-to-SIP video calls.
● Video Border Proxy combines the function of a gatekeeper with a gateway to proxy SIP
and H.323 video calls. The video border proxy currently supported is the Polycom VBP-E
series for H.323 video calls. The Polycom VBP-E series is supported only when the VBP-E
is trunked to the Polycom CMA and the CMA is neighbored to Communication Manager
configured as an Evolution server with an Avaya H.248 gateway, such as the Avaya G430
Branch Gateway.
● Gateways provide SIP-to-H.323 video interworking. Communication Manager configured
as an Evolution server with an Avaya H.248 gateway, such as the Avaya G430 Branch
Gateway, serves that role. The Polycom RMX is supported when configured as an
H.323-to-H.320 gateway. It provides interoperability with video endpoints on public ISDN
communication services.
● Conferencing bridges, aka Multimedia Conferencing Units (MCU), support content
sharing between video endpoints. The Avaya 1040 and 1050 video endpoints provide that
functionality. They have embedded 4- and 6/8-port MCUs, respectively. The Polycom
RMX-series HD MCU is also supported.
● Conferencing scheduling and endpoint management applications manage and
monitor video endpoints. Avaya Video Conferencing Manager manages and monitors the
Avaya 1000-series endpoints on Session Manager. The Polycom CMA manages and
monitors Polycom video endpoints.
● Endpoints are the desktop and conference room devices that deliver audio and video.
Within AVCS, several video endpoints register directly with Session Manager: the Avaya
1000-series, Avaya one-X
®
Communicator, and Polycom HDX series. The Polycom HDX
H.323 and BSX H.323-series register to Communication Manager configured as an
evolution server with an Avaya H.248 branch gateway. Additional supported H.323
endpoints include the Tandberg MXP.
