What's New in this Release
This section contains information about new features and functionality added in this release.
CTI Load Balancing allows Cisco UC Integration for Microsoft Lync to use Cisco Unified Communications Group information to determine which CTI server to use.
A CTI device typically has a one to one mapping to a Device Pool and each pool has a one to one mapping with a Cisco Unified Communications Manager group. That group has one of more Cisco Unified Communications Manager servers associated with it. Cisco UC Integration for Microsoft Lync will use the first two highest priority servers in the group when CTI Load Balancing is enabled. These two servers become the primary and secondary CTI servers. These servers override any other CTI server settings.
Select Admin > System > Cisco Unified CM Groupin Cisco Unified Communications Manager to view group information.
This feature is enabled by creating the registry key UseCUCMGroupForCti and setting the value to true. The application will first search for this value in HKEY_CURRENT_USER\Software\Cisco Systems, Inc.\Client Services Framework\AdminData and then HKEY_CURRENT_USER\Software\Policies\Cisco Systems, Inc.\Client Services Framework\AdminData.
If the desktop phone device configuration file is encrypted but the software phone device configuration file is not encrypted, the CUCM Group information contained in the software phone device configuration file will be used. If no software phone device configuration file is present, the CTI server information cannot be obtained by this method.
Cisco Virtualization Experience Media Engine
The Cisco UC Integration for Microsoft Lync installer comes bundled with Cisco Virtualization Experience Media Engine (VXME) software called VXME Utilities. This software supports Cisco Unified Communications in virtual environments. These utilities include the Device Selector. Virtual users can manage their audio and video devices with the Device Selector.
Desktop sharing is not supported when Cisco UC Integration for Microsoft Lync is running in a virtual environment using Cisco VXME.
