Dell ThinOS 2211, 2208, and 2205 Administrator’s Guide

Cisco Webex Meetings Virtual desktop software is the Unified Communications product from Cisco for real-time video conferencing in a VDI environment. It supports audio-video conferencing on the hosted virtual desktops. Cisco Webex Meetings offloads media processing from the virtual desktop server to the thin client. All audio and video signals are routed directly between the endpoints without going through the hosted desktop. From version 41.12.6.12.1, registration and invitations in Webex Meetings and Webex Events can be managed by cohosts. Cohosts can import or invite attendees and event panelist. Cohosts can also approve or reject registrants. Cisco Webex Meetings VDI version 41.12.6.12.1 supports optimization mode through HTTP proxy server with username and password authentication.

Cisco Webex Meetings Virtual Desktop software enables you to attend meetings in a VDI environment. Cisco Webex Meetings for VDI consists of the following components:

  • Key—Computer\HKEY_CURRENT_USER\Software\\Cisco Systems, Inc.\CiscoVDI
  • Values:
    • Name—isVDIEnv
    • Type—REG_EXPAND_SZ
    • Data—true
  NOTE:Restart Webex Meetings after you edit the registry.
