Here, you can activate or deactivate the virtual desktop optimization for Cisco Webex and define settings for the Cisco JVDI client.

Cisco Webex Meetings VDI

This virtual desktop optimization contains a media engine and redirects the audio and video streams so that they are exchanged directly between the endpoint devices and Webex Meetings cloud, without going through the hosted virtual desktop in the datacenter. 

Make sure both your client-side Cisco Webex Meetings plugin and the server-side application have the same version. Otherwise, the Cisco Webex Meetings VDI solution might not work.

To select the version of the Cisco Webex Meetings plugin:

  1.  In the UMS configuration dialog or the local Setup, go to System > Registry > multimedia > ciscomeetings > activeversion.
    (If you do not see the corresponding version, but it is listed in the release notes, please update the firmware your profile is based on.)
  2. Select the desired version and click Apply or Ok.

For further information, see the Cisco documentation for WebEx Meetings:

☑The Cisco Webex Meetings VDI solution is enabled.

☐The Cisco Webex Meetings VDI solution is disabled.
