The TANDBERG VCS
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 can act as a standards-based
TURN server.
The VCS Expressway is normally deployed outside of your firewall or within the DMZ.
