You can make optimized audio and video calls with Skype for Business inside a virtual desktop without negatively affecting the virtual infrastructure and overloading the network.

All media processing takes place on the client machine instead of in the virtual desktop during Skype audio and video call.

To use Skype for Business, you must install the Virtualization Pack for Skype for Business feature on the client machine during Horizon Client for Windows installation. See the Using Vmware Horizon Client for Windows document.

A Horizon administrator must install the Virtualization Pack for the Skype for Business feature on the virtual desktop during Horizon Agent installation.

  • If you are connected to a private network when you install Skype for Business on the remote desktop, the installer adds inbound and outbound firewall rules for that network profile.

To fix the problem, manually add firewall exceptions for Skype for Business client in the firewall rules for all network profiles.

  • The volume control option in the remote desktop operating system does not affect the volume level of an ongoing Skype call. Use the volume control in the Skype call or use the volume control on the client machine to make volume changes.
