Cisco TelePresence Video Communication Server Control

Cisco TelePresence Video Communication Server Control (Cisco VCS Control) provides advanced telepresence

applications and session management to all standards-compliant telepresence endpoints, infrastructure, and

management solutions. Cisco VCS Control provides Session Initiation Protocol (SIP) proxy and H.323 gatekeeper

services, enabling any-to-any interoperability between SIP and H.323 telepresence devices. Cisco VCS Control is

a critical part of Cisco’s unified call-control solution and is also critical for interoperability with third-party unified

communications and IP telephony networks and voice-over-IP (VoIP) solutions (Figures 1 and 2).

Cisco TelePresence Video Communication Server Expressway

Cisco TelePresence Video Communication Server Expressway (Cisco VCS Expressway) opens the world outside

the firewall to organizations using video communications (Figures 1 and 2). Cisco VCS Expressway enables

business-to-business communications, empowers remote and home-based workers, and allows service providers

to provide video communications to customers. Cisco VCS Expressway provides standards-based and secure

firewall traversal for SIP and H.323 devices and enables communication with the outside world regardless of SIP

or H.323 protocol.
