Optimized mode and Fallback mode
In Optimized mode, the Skype for Business delivers an optimal performance. In Fallback mode, the Skype For Business calls
are not optimized. On the lower right of the virtual desktop, the tooltip of the Virtualization Pack icon indicates the VMware
Horizon Virtualization Pack for Skype for Business mode.
The following screenshot displays the Virtualization pack for Skype for Business in Optimized mode:
Figure 35. Optimized mode
If the Optimized mode icon is not displayed, the Virtualization Pack is running in Fallback mode. This is because of the version
mismatch between the Horizon Client on the thin client and the Horizon Agent on virtual desktop.
For information about compatibility of Horizon Virtualization Pack for SFB components, see the Horizon Client 4.8 or later and
Agent 7.5 or later Virtualization Pack for Skype for Business is not compatible with older Client and Agent releases article at
