calls.
Note that:
VCS defines an "audio-only" SIP call as one that was negotiated with a single "m=" line in the SDP. Thus,
n
for example, if a person makes a "telephone" call but the SIP UA includes an additional m= line in the SDP,
the call will consume a video call license.
While an "audio-only" SIP call is being established, it is treated (licensed) as a video call. It only becomes
n
licensed as "audio-only" when the call setup has completed. This means that if your system approaches its
maximum licensed limit, you may be unable to connect some "audio-only" calls if they are made
simultaneously.
TMS Agent functionality removed
TMS Agent (legacy mode) functionality has been removed. Instead, if you use TMS provisioning, you must
use TMS Provisioning Extension services.
Java application removed
The Java application has been removed. This removes the threat of Java security vulnerabilities.
OCS Relay functionality and Microsoft OCS 2007 zone profile removed
OCS Relay functionality and the Microsoft Office Communications Server 2007 zone profile have been
removed. The Cisco AM GW configuration options previously under the VCS configuration menu, and the
Cisco Advanced Media Gateway zone profile have also been removed.
Instead, we recommend that you use the Microsoft Lync B2BUA to route SIP calls between the VCS and a
Microsoft Lync Server, and to configure your Cisco AM GWs as B2BUA transcoders. Note that B2BUA
connections to Microsoft OCS are no longer supported from X8.1.
Support for Active Control
VCS supports Active Control (iX Channel passthrough) as supported by Cisco TelePresence Server 3.1 or
later and endpoints running TC6.2 or later. It can be configured on a per-zone basis.
FIPS140-2 cryptographic mode
VCS has implemented FIPS140-2 compliant features.
New VMware installations
New VMware installations have a choice of 3 .ova files: Small (for Cisco Business Edition 6000
deployments), Medium (for typical deployments) or Large (for large-scale deployments). Note that the VM
.ova files are used for new installations only. Do not use them to upgrade your existing VM installation.

configurations and their associated memory and CPU resource reservation requirements.
ICE messaging support
ICE messaging support is now configurable at the zone and subzone level.
Certificate management
The certificate management pages are now located under
The management of CA certificates has been improved, allowing you to view, upload and delete individual
n
CA certificates.
