VDI client registry settings

Specify the port ranges when connecting with UDP. The default range used by zoom is 17000 - 17100 if no UDP Port Begin/End is specified.

The range must fall between 1000 - 64000, and the specified range should be no greater than 100 ports. If there are multiple users sharing the same VM machine, reserving 8 ports for each user is recommended. Before testing UDPPortBegin-End, ensure the following policies are configured as such:

• DisableUDPBridge is disabled (0)
• DisableICABridge is enabled (1)
• DisableMMRDirect is enabled (1)
• A new Firewall inbound rule, example: (63000-63100)

Zoom VDI client and plugin Global minimum version or higher

If your thin client cannot connect to the Virtual Desktop VM by UDP, enabling this policy prevents any UDP connection between VM and thin client, which may in turn speed up the process of joining a meeting.

Note: If this is configured on the thin client, those settings will override the settings on the VM.

By default, there are no restrictions. Enabling this policy will prevent ICA connections.

If the MMR is inaccessible for the thin client, the UDP connection from the thin client to the VM is not available, and this policy is enabled, the client will display the "Zoom Plugin can not connect to the server according to your Zoom config and network status" message and attempts to join or start meetings will fail.

Note: If this is configured on the thin client those settings will override the settings on the VM.

If your firewall has blocked the zoom connection process to Zoom MMRs on thin clients, enabling this policy may speed up the process of joining a meeting.

Note: If this is configured on the thin client those settings will override the settings on the VM.

By default, there are no restrictions. Enabling this policy will prevent connections between the thin client and Zoom Phone servers.

If your network firewall prevents the Zoom process from connecting to the Zoom Phone Server on the thin client, enabling this policy may speed up the process of connecting to Zoom Phone calls. If this is configured on the thin client, those settings will override the settings on the virtual desktop. 

By default, there are no restrictions. Enabling this policy will prevent sending Zoom Phone audio over a UDP connection from the thin client to the virtual desktop

If your thin client cannot connect to the virtual desktop over UDP, enabling this policy may speed up the process of making a call. If this is configured on the thin client, the settings will override settings on the virtual desktop. 

By default, there are no restrictions. Enabling this policy will Prevent sending Zoom Phone audio over a channel connection, such as the ICA protocol connection channel.

If your configuration is expected to use Direct or UDP, enabling this policy will prevent Zoom Phone from sending Zoom Phone audio over another protocol channel. 

When this policy is enabled, determining which Zoom server to connect to for meetings is based on the location of the thin client where the VDI plugin is located. If your thin clients are located in a different geographical location than your virtual desktops, enabling this configuration can reduce join time and latency, as a more local server connection may be chosen instead.

PingServerFromThinClientOffloadConfRequest

By default, the VDI virtual machine uses the plugin’s public IP address to determine and connect to the most suitable Zoom Servers. This requires the PingServerFromThinClient policy to be set to 1.

This requires VDI version 5.14.10 or higher.

(0) - Ping from VDI VM and use the plugin’s public IP address to select the most suitable Zoom Zone Center (Default)
(1) - Ping from thin client.

Note: This policy will no longer be supported with version 6.2.10 and higher.

Note: DSCP marking must be enabled in the Zoom web portal for this to function on the plugin side.

Applies DSCP tagging for audio and video traffic using the specified values. If using any values besides the default (40 for video, 56 for audio), DSCP tagging requires admin privileges and the EnableIndependentDataPort policy is enabled.

Both values must be set for DSCP tagging to be applied and must be between 1 and 63. Otherwise, the value from the Zoom web portal (account settings) is used. These policies override the account settings if set, and don't require the user to be logged in to an account.

Note: If a line return is required, "\n" should be used to add the line return.

Note: If a line return is required, "\n" should be used to add the line return.

By default, the VDI client will force the thin client power settings to high-performance mode. Enabling this policy prevents high-performance mode from being automatically enabled.

This policy only affects thin clients with a 2-core CPU or less.

PhoneCallTipMsg

This policy disables the audio quality popup message. This requires Zoom VDI client version 5.15.2 or higher

(0) - (Default) "Poor network connection. Audio quality may be affected" notifications during phone calls will be displayed as needed. 
(1) - "Poor network connection. Audio quality may be affected" notifications during phone calls will be disabled. 

DisableAWSPlatform

This policy disables connection attempts from the VDI meeting client to the VDI plugin for AWS WorkSpaces. 

(0) - (Default) Connections to AWS WorkSpaces platform are enabled. 

(1) - Connections to AWS WorkSpaces platform are disabled. 

Disabled by default, enabling the policy enables the VDI plugin auto-update to install or upgrade VDI plugins if the VDI auto-update component has been installed on the thin client. This feature is currently only supported for Windows devices.

Adding this policy to the Windows Thin Client can be used to disable the auto-update feature for a specific device. For example, adding the policy to managed devices to disable updates internally, while disabling auto-update to update users' personal devices at home.

• This requires Zoom VDI client version 5.10.0 or higher.
• VDI Plugin Management software on client
  • Zoom VDI Plugin for Windows version 5.9.6 or higher
  • Zoom VDI Plugin for macOS version 5.12.6 or higher

This policy specifies the Auto-update plugin version and will give priority to the specified version. If the specified version is not supported, the web server configuration will be used.

The plugin version must fall within a range of acceptable values that apply to each version of the host client. Values that are out of range will be ignored, and a value best suited for the host value will be used instead.

Note: A complete list of supported versions is available in the VDI plugin and Auto-Update plugin versions article/

• This requires Zoom VDI client version 5.9.6 or higher
• VDI Plugin Management software on client
  • Zoom VDI Plugin for Windows version 5.9.6 or higher
  • Zoom VDI Plugin for macOS version 5.12.6 or higher

This policy specifies the Auto-update plugin version for Windows and will prioritize the specified version. If this setting is not configured (empty), the update behavior will fall back to the AutoUpdatePluginVersion behavior.

This policy specifies the Auto-update plugin version for Mac and will prioritize the specified version. If this setting is not configured (empty), the update behavior will fall back to the AutoUpdatePluginVersion behavior.

(0) Default (plugin auto-update later option is disabled)
(1) Include the Later option, which closes the dialog. The next time the user connects, the same dialog will be presented if the VDI plugin management software detects an action is still required. This policy requires Zoom VDI client version 5.11.6 or higher.
(2) Include the Later option, which waits until the user disconnects from their virtual desktop(s) and then performs the update. This policy requires the Zoom VDI client version version 5.13.0 or higher.

0 - (default)  Plugin auto update opt out is not enabled. (Plugin auto update is enabled)

1 -  Plugin auto update opt-out is enabled. (Plugin auto update is disabled)

This policy provides administrators with the ability to customize the opt-out dialog text in the VDI Plugin Management prompt dialog. If left empty, the default text will be used

Note: If a line return is required, "\n" should be used to add the line return.

By default when the plugin is auto updating, the progress of the installation will not be displayed and the update will be silently installed. If enabled, users will be shown the progress of the update.

  
(0) Default (The installation process will not be displayed)

(1) Enabled, plugin MSI installation from plugin auto update will show MSI progress dialog

By default for versions 5.16.10 and higher, the VDI client will not check signatures for DLL files in the VDI plugin installation path, in order to start more quickly. This policy can be enabled to force the the signature checks. 

(0) Skip the signature checks. 

(1) Force signature checks. 

ForceSilentVDIPluginUpdate

This policy provides administrators with the option to detect an outdated or missing plugin. It also provides the option to download and install the required VDI Plugin after the user disconnects from their virtual desktop without prompting or informing the user that a new VDI Plugin is being downloaded and installed.

This policy determines if Zoom checks if Microsoft Teams is running.

By default, the VDI client will check if Skype for Business or Teams are running. The default behavior checks for the lync.exe process. That check was added in 5.10.6. In 6.0.10, this was updated to look for msteams.exe. If either process runs, the VDI Zoom Workplace client will not attempt to enable HID for the selected device. If this policy is added and enabled, the client will not check for either process.

Note: Not checking may not result in HID support becoming available for the VDI Zoom Workplace client; however, if another application is already using HID for the selected device.

• (1) Video is required to be on during the entire meeting and the user cannot disable it. Audio can still be muted/unmuted as needed.
• (2) Video and computer audio are disabled, and only connecting to audio through phone dial-in or call-me is allowed. For a PMI meeting, the host still needs to check the telephone and computer audio settings before starting. The VDI client will enable computer audio if the host has enabled it on the PMI.

   

Note: This key must be used in the HKLM hive.

(Beta) This policy can be used to offload screen capture commands to the plugin side, where the screenshot can capture video received by the VDI plugin. This requires VDI version 5.14.10 or higher.

Currently, the default is disabled (1), but may be changed in a future release.

By default, the Green Room feature will be enabled.
