 # Quickstart: Manage a room call
 
 ## Introduction
-Once Azure Communication Services (ACS) room call has been successfully started, the call can be managed using Calling SDKs, Call Automation SDKs or both. In a room call, the mid-call actions are controlled by either the roles assigned to participants and properties configured in the room.
+Azure Communication Services (ACS) room call is started, the call can be managed using Calling SDKs, Call Automation SDKs or both. In a room call, the mid-call actions are controlled by either the roles assigned to participants and properties configured in the room.
 
 ## Calling SDKs
 Calling SDK is a client side calling libraries enabling participants in a room call to perform several mid-call operations (e.g. screen share, turn on/off video, mute/unmute, etc. ). Full list of capabilities offered in Calling SDK is listed in the [Calling SDK Overview](../../concepts/voice-video-calling/calling-sdk-features.md#detailed-capabilities)
 
-The capabilities are controlled based on roles assigned participants in the call (e.g. Only presenter can screen share). Please refer to this [Rooms Concepts](../../concepts/rooms/room-concept#predefined-participant-roles-and-permissions) for participant roles and permissions.

 ## Call Automation SDKs
 Call Automation SDK is a sever side libraries enabling administrator to manage an ongoing room call in a central and controlled environment. Unlike Calling SDK, Call Automation SDK operations are roles agnostic. Therefore, a call administrator may perform several mid-call operations on behalf of the room call participants.

+### Connect to a room call
 Call Automation must connect to an existing room call prior to performing any mid-call operations. CallConnected or ConnectFailed events are notified using callback mechanism to indicate a connect operation is successful or failed respectively.

-Once connect action succeeds, a CallConnect event is notified via Callback URI. The ```callConnectionId``` is available such that it can be used to retrieve a call connection object on the room call that it has just successfully connected. ```callConnectionId``` will be used to retrieve a callConnection object in the following mid-call actions.

 ### Add PSTN Participant
-Call Automation can dial out to a PSTN number and add the participant into a room call. A room, however, must be set up to enable PSTN dial-out option (EnabledPSTNDialout is set to true) and Azure Communication Services (ACS) resource must have a valid phone number. Please refer to Rooms [Quickstart](get-started-rooms?tabs=windows&pivots=platform-azcli#enable-pstn-dial-out-capability-for-a-room) for detail.
