 # How to control mid-call media actions with Call Automation
 
-[!INCLUDE [Public Preview Disclaimer](../../includes/public-preview-include-document.md)]
-
 Call Automation uses a REST API interface to receive requests for actions and provide responses to notify whether the request was successfully submitted or not. Due to the asynchronous nature of calling, most actions have corresponding events that are triggered when the action completes successfully or fails. This guide covers the actions available to developers during calls, like Send DTMF and Continuous DTMF Recognition. Actions are accompanied with sample code on how to invoke the said action.
 
 Call Automation supports various other actions to manage calls and recording that aren't included in this guide.
