The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality.

Because of a limitation known as the hairpin effect , calling, meeting, and accompanying video capability are not supported without optimization.
The additional bandwidth required for calls and video creates a bottleneck at the data center because the media flows from one user to the data center back to another user. As a result of this unoptimized media path and the lack of easy access to peripherals such as device speakers, microphone, and camera, the user experience is not ideal. To fix the issue of the hairpin effect, the Webex App VDI plugin extends the Cisco collaboration experience to virtual deployments so that users can use the full messaging, meeting, and calling functionality that the Webex App provides.
To reduce latency and to enhance media quality, the VDI plugin optimizes the media workflows by streaming media directly between users on thin client endpoints and leverages the hardware of the thin client machines to handle media processing. This media path does not go through the hosted virtual desktops HVDs.
The result is a stable and full-featured calling and meeting experience for your VDI users. In this architecture, the Webex App is installed on the HVD in your VDI environment and required VDI plugins are installed on the user’s thin client typically a lightweight system, like a repurposed laptop or desktop. With supported versions of Webex App , users can use all of the built-in messaging, meetings, and calling on Webex App functionality on their thin client. The Webex App on the virtual desktop still processes lightweight data such as call signaling and retrieving configuration from the cloud.
For new features for each release, see the release notes for more information. Using Webex App in an optimized virtual environment requires the following components. Connection broker —The resource and connection manager Citrix, VMware that connects the virtualization provider to the thin client. Thin client —The endpoint for example, low profile or repurposed desktop or laptop that the user uses to sign in remotely to the virtual desktop.
Plugin —Software that is installed on the thin client used to offload media processing to the user device instead of HVD resources. Persistent mode —In a persistent environment, a user’s local operating system changes are preserved after a user signs out.
Non-persistent mode —In a non-persistent environment, a user’ local operating system changes are not preserved after a user signs out. The applicable user-specific information user data, profile, and settings is cached during the user session. The roaming database contains all user credentials and preferences, encrypted using AES As a VDI customer, you should always back up the roaming database, so that user credentials and preferences are maintained across VDI sessions.
The architecture diagrams show the components, signaling, and optimized media flows that are involved in a typical Webex App VDI deployment with an existing supported call service deployment: either Unified CM, Webex Calling, or BroadWorks. On the left of each diagram is your corporate network which contains the virtual environment. Automatic upgrade of the plugins is only available with Webex App Automatic upgrade of the plugin is supported on Windows and MacOS thin clients.
The plugin does not automatically upgrade on Linux thin clients. The plugin can only upgrade automatically if the Webex App on the virtual desktop also upgrades automatically. Users are prompted to upgrade the plugin after the Webex App has upgraded on the virtual desktop.
We recommend that you keep the plugin and the virtual desktop Webex App on the latest version. There is some backwards compatibility if you can’t upgrade them together. See “Version support” in the Release notes for more information. Keep this information in mind as you manage upgrades or changes to your Citrix or VMware connection brokers.
Be sure to use the supported versions that are listed in the Prepare Your Environment chapter. You and your users see a warning in the VDI plugin installation steps that reminds you to install the connection broker first. If you see an upgrade notice in the Citrix environment, performing this upgrade does not affect the Webex App VDI plugin on a Windows or Mac thin client.
If you see an upgrade notice in the Citrix environment, you must reinstall the Webex App VDI plugin on a Linux thin client after upgrading your Citrix environment.
You and your users see a warning in the VDI plugin installation steps that reminds you to install the connector broker first. After this configuration, Webex App runs on the non-optimized solution. Rename TSDetectionLib. You must either rename the file back to TSDetectionLib. By modifying the registry, you can enable or disable specific Webex App features such as high definition HD and screen sharing.
Doing so can save resources on the server in the data center. You can also decide whether users can do full or HVD window only screen share. If your users are on systems that are capable of more advanced video features, you can enable the features as needed. You can modify the registry keys before or after the VDI plugin is installed. Changes to the Windows registry should be done with extreme caution. We recommend that you make a backup of your registry before using these steps.
Make sure your users’ thin client devices meet the system requirements for virtual backgrounds. In Windows search or the Run window, type regedit and then press Enter. In fallback mode, datacenter load increases, so to prevent overload, media is not used. Users can dismiss the reminder if they want. The reminder appears weekly until users take action. Users can also dismiss this notification. As an administrator, you can enable or disable these notifications at the organization-wide level.
Problem On Linux VDI clients, the ringtone for an incoming call does not ring all devices including speakers on the thin client even if that option is selected in Webex App on the HVD host. Only the audio device selected on the HVD plays the ringtone.
If a Linux thin client user is observing this ringback tone issue, set the value of this key to 1. The diagnostics available in the Webex App desktop and VDI help you and your users resolve connection issues, check media quality, and collect important troubleshooting information.
When you set up Calling in Webex App Unified CM , you may encounter issues related to the connection or required settings such as voice domain and UC services. Using this tool, you can diagnose what services are configured correctly and what is missing. This feature is useful for troubleshooting scenarios and reducing support cases, whether you’re migrating to Calling in Webex App Unified CM or setting up new users. When user experience issues, they can access the diagnostics view and export the data to share with you or support.
Unified CM Settings —Critical settings for Jabber migration as well as new user setup for phone services to work correctly, such as:. Media quality —Quality for video, audio, and sharing in both directions. Devices —Device information, when users are connected to devices. For shortcut keys to show the diagnostics window, see Keyboard and navigation shortcuts.

A connection broker performs a number of tasks including the following: Validating the username and providing a connection for the user.
