TANDBERG Video Communication Server bridge

Cisco VCS Infrastructure box

Note: The Tandberg Video Communication Server (VCS) was made End Of Life and replaced by the Cisco Video Communication Server (VCS).


The TANDBERG Video Communication Server bridges the gap between SIP and H.323 and delivers three unique applications in one centralized device.

It features innovative video call forwarding capabilities through TANDBERG FindMe™and extends SIP support to network administration and firewall traversal.
