-- When using [Call Automation](../../../call-automation/callflows-for-customer-interactions.md), you have two options to get the `serverCallId`:
-    1) Once a call is created, a `serverCallId` is returned as a property of the `CallConnected` event after a call is established. Learn how to [Get CallConnected event](../../../call-automation/callflows-for-customer-interactions.md?pivots=programming-language-python#update-programcs) from Call Automation SDK.
-    2) Once you answer the call or a call is created, it returns the `serverCallId` as a property of the `AnswerCallResult` or `CreateCallResult` API responses respectively.
+When using [Call Automation](../../../call-automation/callflows-for-customer-interactions.md), you will receive the `callConnectionId` from the response event from a `createCall`, `answer`, or `connect` requests when initiating the call.

+### How to fetch serverCallId
 
-- When using [Calling Client SDK](../../get-started-with-video-calling.md), you can retrieve the `serverCallId` by using the `server_call_id` variable on the call.

 To produce unmixed audio recording files, you can use the `AudioChannelParticipantOrdering` functionality to specify which user you want to record on channel 0. The rest of the participants are assigned to a channel as they speak. If you use `RecordingChannel.Unmixed` but don't use `AudioChannelParticipantOrdering`, Call Recording assigns channel 0 to the first participant speaking.
