future maintenance release.
Citrix multiple virtual channels
Citrix Workspace App 2012 has a virtual channels count limitation. The current Zoom Meetings Optimization plug-in uses four
virtual channels. To use Zoom Optimizations together with Microsoft Teams or any other Cisco optimizations, you must disable
other virtual channels. For example, if you are not using Imprivata SSO you can choose to disable the Imprivata virtual channel.
Similarly, if you do not use Skype for Business, you can choose to disable the RTME for Skype for Business virtual channel.
NOTE: Configuring Session Settings > Citrix Session Settings > Keyboard Layout Mode to use Dynamic Sync uses
an additional virtual channel.
You can configure the virtual channels settings either using the Wyse Management Suite policy or Admin Policy Tool. To
configure the virtual channel settings, do the following:
1. Open the Admin Policy Tool on the ThinOS client or go to ThinOS 9.x policy settings on Wyse Management Suite.
2. On the Advanced tab, expand Session Settings, and click Citrix Session Settings.
3. In the UC Virtual Channel Settings section, enable or disable one or more Unified Communications (UC) virtual channels.
4. In the Other Citrix Virtual Channels Settings section, enable or disable other Citrix virtual channels such as USB
Redirection and Imprivata.
The following combinations are the Unified Communication (UC) optimizations and their default virtual channel settings that are
tested for ThinOS 9.1:
