TANDBERG VIDEO COMMUNICATIONS SERVER

ADMINISTRATOR GUIDE

Zones and Neighbors

This section begins with an overview of all the different types of subzones and zones and how these fit into the overall structure of your video communication network.

It then provides information on the pages that appear under the Local Zone, Zones and Alternates sub-menus of the VCS Configuration menu.

These pages allow you to:

•

•

•

configure the VCS’s Local Zone (which is made up of subzones, including the Traversal Subzone and Default Subzone)

create and configure external zones to communicate with other systems and endpoints, including other VCSs, Gatekeepers, Border Controllers or SIP devices, and endpoints contactable via DNS or ENUM dialing.

create VCS Clusters to increase the capacity of your local zone, and for resiliency.
