What's New In This Version; X8.1.1; X8.1 - Cisco TelePresence Administrator's Manual

Introduction

What's new in this version?

The new features introduced in this release of VCS software are described below.

X8.1.1

Unified Communications: mobile and remote access
Cisco Unified Communications mobile and remote access is a core part of the Cisco Collaboration Edge
Architecture. It allows endpoints such as Cisco Jabber to have their registration, call control, provisioning,
messaging and presence services provided by Cisco Unified Communications Manager (Unified CM) when
the endpoint is not within the enterprise network. The VCS provides secure firewall traversal and line-side
support for Unified CM registrations.
For more information including configuration recommendations and troubleshooting details, see
Communications: Mobile and Remote Access via VCS Deployment
Support to modify Maximum transmission unit (MTU) size
You can configure the maximum transmission unit (MTU) for each network interface on the
page.
Changed functionality
The tcpdump facility has been removed from the
Jabber Guest
Jabber Guest support has been removed (it was previously provided as a feature preview in X8.1). It will be
reintroduced in a future release of VCS software.

X8.1

Microsoft Lync 2013 / H.264 SVC support
The Microsoft Lync B2BUA now supports calls to and from Microsoft Lync 2013 clients. It provides
interworking between standard H.264 AVC and Lync 2013's H.264UC SVC codec. To use Lync 2013 you
must install the Microsoft Interoperability option key (formerly known as the Enhanced OCS
Collaboration option key). Note that for Lync 2010, the Microsoft Interoperability option key requirements
remain as per previous releases (i.e. it is required for encrypted calls to and from Microsoft Lync Server and
for establishing ICE calls to Lync clients).
Presentation sharing via Lync 2013 is supported but only from VCS to Lync.
Support for standards-based H.264 SVC codecs
The B2BUA now supports calls to standards-based H.264 SVC codecs.
Improved performance and scalability
VCS X8.1 software can take advantage of the improved performance and scalability capabilities that are
n
available when running on Large VM server deployments. It can support up to 500 traversal calls, 750 non-
traversal calls and 5000 registrations. Note that standard VCS appliances or equivalent VM hardware still
provides support for up to 150 traversal calls, 750 non-traversal calls and 2500 registrations.
The number of concurrent searches has increased from 100 to 500.
