-Azure Communication Services Call Automation provides developers the ability to build server-based, intelligent call workflows for voice and PSTN channels. The SDKs, available for .NET and Java, uses an action-event model to help you build personalized customer interactions. Your communication applications can listen to real-time call events and perform control plane actions (like answer, transfer, play audio, etc.) to steer and control calls based on your business logic.

 - Integrate your communication applications with Contact Centers and your private telephony networks using Direct Routing.
 - Protect your customer's identity by building number masking services to connect buyers to sellers or users to partner vendors on your platform.
 - Increase engagement by building automated customer outreach programs for marketing and customer service.
+- Analyze in a post-call process your unmixed audio recordings for quality assurance purposes.  
 
 ACS Call Automation can be used to build calling workflows for customer service scenarios, as depicted in the high-level architecture below. You can answer inbound calls or make outbound calls. Execute actions like playing a welcome message, connecting the customer to a live agent on an ACS Calling SDK client app to answer the incoming call request. With support for ACS PSTN or Direct Routing, you can then connect this workflow back to your contact center.

 **Transfer** – When your application answers a call or places an outbound call to an endpoint, that endpoint can be transferred to another destination endpoint. Transferring a 1:1 call will remove your application's ability to control the call using the Call Automation SDKs.
 
+**Record** - You decide when to start/pause/resume/stop recording based on your application business logic, or you can grant control to the end user to trigger those actions.

 **Hang-up** – When your application has answered a one-to-one call, the hang-up action will remove the call leg and terminate the call with the other endpoint. If there are more than two participants in the call (group call), performing a ‘hang-up’ action will remove your application’s endpoint from the group call.
 
 **Terminate** – Whether your application has answered a one-to-one or group call, or placed an outbound call with one or more participants, this action will remove all participants and end the call. This operation is triggered by setting `forEveryOne` property to true in Hang-Up call action.
