How I know who finished the call

Hi community.

I'm working with the Microsoft Graph Api.

I'm getting information about the call records, how can i know who finished the call? and if this user location is office or remote.

Here you have the endpoints i use
https://graph.microsoft.com/v1.0/communications/callRecords
https://graph.microsoft.com/v1.0/communications/callRecords/getDirectRoutingCalls

Thanks!
