Dell Wyse ThinOS Version 8.6 and ThinOS Lite 2.6 Operating System Release Notes

VMware Horizon Virtualization Pack for Skype for Business

The VMware Horizon Virtualization Pack for Skype for Business enables you to use Skype for Business in a VMware Horizon desktop. Microsoft Skype for Business is a unified communications platform that delivers an optimized user experience for online messaging, audio, and video calling and so on.

ThinOS supports VMware Horizon Virtualization Pack for Skype for Business in a Blast session. PCoIP and RDP protocols do not support this feature.

NOTE:

For information about configuring Skype for Business, and Optimized and fallback modes in Skype for Business, see the Dell Wyse ThinOS Version 8.6 Administrator's Guide at www.dell.com/support.
For information about the Horizon Agent installation, see the Setting Up Virtual Desktops in Horizon 7 document at docs.vmware.com.

NOTE: Horizon Client 4.8 or later and Horizon Agent 7.5 and later are not compatible with older Client and Agent releases. Due to this limitation, when you use the Horizon Client 4.8 and Horizon Agent 7.5 with older client and agent releases, Skype for Business calls run in fallback mode and calls are not optimized. Ensure that you review the compatibility matrix of Horizon Virtualization Pack for SFB components at kb.vmware.com/s/.
