Missing graph api to get microsoft teams call history of external users #1695

Hi Microsoft Support Team,

My issue is related to Microsoft Graph APIs.

When I make a call to an internal user, or an internal user calls me, I am able to retrieve the call history using the Graph API. However, when I make a call to an external user, or an external user calls me, the call history is not available through the API.

I am using the following endpoint to fetch call history:
https://graph.microsoft.com/v1.0/communications/callRecords

I have already set up the subscription event and the notification webhook, which successfully notifies me whenever a call is made.

Please let me know how I can make a call to an external user and also retrieve the call history for those external calls.

Internal user: Who is already in my azure account
External user: Who is not already in my azure account

Please get back to me with a proper solution as soon as possible, as both I and my customers are losing confidence in the system due to this missing functionality.

Thank you.
