Scenarios Where VbSS Content Sharing Reverts to RDP
In calls involving systems and Skype for Business clients, content sharing can revert to RDP when VbSS
isn't supported.
Displayed content is not interrupted when reverting to RDP (you should only see a notification that VbSS
isn't being used). Once reverted, RDP is used for the remainder of the call.
VbSS content sharing reverts to RDP in the following scenarios:
• Recording a call
• Sharing an application
• Taking control of a desktop sharing session
• Joining a call with a system or client that doesn't support VbSS
• Sharing content with audio (also applies to RDP)
For more detailed information on these scenarios and others, see the following table.
