The TANDBERG Video Communication Server (VCS) is an
industry unique multi-application device that enhances the video
experience with new functionality and provides transparent
communication between SIP and H.323 endpoints. It allows
you to manage endpoint registrations and calls, and control the
bandwidth being used within your network. The VCS also offers
advanced call policy that allows you to accept, reject and re-
route calls.
The VCS forms part of TANDBERG’s Expressway™ firewall
traversal solution, allowing you to securely connect to other
video networks and equipment from your secured private
network.
The VCS is supplied as either of two base applications: VCS
Control and VCS Expressway.
Overview
VCS Control
The VCS Control provides internal video control and
administration for all SIP and H.323 devices. It is normally
deployed within your wide area network with endpoints that are
behind the same firewalls or NAT devices.
The VCS Control replaces the need to have separate H.323
gatekeeper, SIP registrar and H.323 - SIP gateway servers.
VCS Base Applications
VCS Expressway
The VCS Expressway provides standards-based firewall traversal
for SIP and H.323 devices allowing secure firewall traversal of
any firewall or NAT device.
As well as all the functionality of a VCS Control, it also provides
registration of traversal-enabled devices and STUN Discovery
and STUN Relay services.
The VCS Expressway is normally deployed outside of your firewall
or within the DMZ.
