 ## Managing Virtual Rooms calls from the server-side using Call Automation Server SDK
 
 Call Automation SDK empowers developers to manage Virtual Rooms calls from the server-side and execute in-call operations. Call Automation capabilities are being progressively enabled in Virtual Rooms calls. The following table shows the current status of these capabilities. Developers manage and control Call Automation capabilities from the server-side, which operate at a higher level than a call participant's privileges. So Call Automation capabilities aren't controlled through user roles and permissions.
