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.
