About the Cisco TelePresence Video
Communication Server (VCS)
The Cisco TelePresence Video Communication Server (VCS) software simplifies session management and
control of telepresence conferences. It provides flexible and extensible conferencing applications, enabling
organizations to benefit from increased employee productivity and enhanced communication with partners
and customers.
The VCS delivers exceptional scalability and resiliency, secure communications, and simplified large-scale
provisioning and network administration in conjunction with Cisco TelePresence Management Suite (Cisco
TMS).
The VCS interworks transparently with Cisco Unified Communications Manager (Unified CM), bringing rich
telepresence services to organizations with Unified CM. It also offers interoperability with third-party unified
communications, IP telephony networks, and voice-over-IP (VoIP) systems.
The VCS supports on-premises and cloud applications and is available as a dedicated appliance or as a
virtualized application on VMware, with additional support for Cisco Unified Computing System (Cisco UCS)
platforms.
You can deploy the VCS as the VCS Control for use within an enterprise and as the VCS Expressway for
business-to-business and remote and mobile worker external communication. An alternative solution, suited
to small to medium-sized businesses (SMBs), is the VCS Starter Pack Express.
Optional packages that you can deploy include FindMe, Device Provisioning, and Advanced Networking
(VCS Expressway only).
Cisco VCS Administrator Guide (X8.1.1) Page 12 of 507
Introduction
About the Cisco TelePresence Video Communication Server (VCS)

VCS base applications
The VCS is available with alternative base applications as described below.
VCS Control
VCS Control delivers any-to-any enterprise wide conference and session management and interworking
capabilities. It extends the reach of telepresence conferences by enabling interworking between Session
Initiation Protocol (SIP)- and H.323-compliant endpoints, interworking with third-party endpoints; it integrates
with Unified CM and supports third-party IP private branch exchange (IP PBX) solutions. VCS Control
implements the tools required for creative session management, including definition of aspects such as
routing, dial plans, and bandwidth usage, while allowing organizations to define call-management
applications, customized to their requirements.
VCS Expressway
The VCS Expressway deployed with the VCS Control enables smooth video communications easily and
securely outside the enterprise. It enables business-to-business video collaboration, improves the
productivity of remote and home-based workers, and enables service providers to provide video
communications to customers. The application performs securely through standards-based and secure
firewall traversal for all SIP and H.323 devices. As a result, organizations benefit from increased employee
productivity and enhanced communication with partners and customers.
It uses an intelligent framework that allows endpoints behind firewalls to discover paths through which they
can pass media, verify peer-to-peer connectivity through each of these paths, and then select the optimum
media connection path, eliminating the need to reconfigure enterprise firewalls.
The VCS Expressway is built for high reliability and scalability, supporting multivendor firewalls, and it can
traverse any number of firewalls regardless of SIP or H.323 protocol.
Standard features
The primary purpose of the VCS is to provides secure firewall traversal and session-based access to Cisco
Unified Communications Manager for remote workers, without the need for a separate VPN client.
The VCS has the following standard features:
n Provides secure firewall traversal and session-based access to Cisco Unified Communications Manager
for remote workers, without the need for a separate VPN client
n 2500 endpoint registrations on a standard appliance and 5000 registrations on Large VM server
deployments
n SIP Proxy/Registrar
n SIP Presence Server
n SIP Presence User Agent
n SIP and H.323 support, including SIP / H.323 interworking
n IPv4 and IPv6 support, including IPv4 / IPv6 interworking
n H.323 gatekeeper
n QoS tagging
Cisco VCS Administrator Guide (X8.1.1) Page 13 of 507

n Intrusion protection
Optional features
Some VCS features are available by the purchase and installation of the appropriate option key:
FindMe™
FindMe is a unique industry solution that gives individual video users a single alias on which they can be
contacted regardless of location. Users have the ability to log on to a web-based interface and control where
and how they are contacted. The FindMe feature also includes support for Microsoft Lync 2010/2013, which
enables FindMe aliases to register as Lync clients, and for Lync clients to view the presence status of
FindMe aliases.

Introduction
About the Cisco TelePresence Video Communication Server (VCS)

Device Provisioning
The Device Provisioning option key allows VCS to provision endpoints with configuration information on
request and to supply endpoints with phone book information. (Endpoints including Jabber Video, E20, and
the EX and MX Series can request to be provisioned.) All configuration and phone book information is
managed in Cisco TMS. The data is then transferred to the VCS, from where it is distributed to endpoint
clients through the Provisioning Server running on the VCS.
See TMS provisioning and Cisco TMS Provisioning Extension Deployment Guide for more information about
how to configure provisioning.
SIP to Microsoft Lync 2010 / 2013 gatewaying
The Microsoft Lync back-to-back user agent (Lync B2BUA) on the VCS can be used to route SIP calls
between the VCS and a Microsoft Lync Server. It provides interworking between Microsoft ICE (used by
Lync clients) and media for communications with standard video endpoints.
The Microsoft Interoperability option key is required for all types of communication with Lync 2013.
Advanced Networking
The Advanced Networking option enables the LAN 2 Ethernet port on the VCS Expressway, allowing you to
have a secondary IP address for your VCS. This option also includes support for deployments where the
VCS Expressway is located behind a static NAT device, allowing it to have separate public and private IP
addresses.
This configuration is intended for deployments where the VCS Expressway is located in a DMZ between two
separate firewalls on separate network segments.
