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.
