This can be a simplified way to fetch all CallRecordsID for MS Teams. Many customers are facing the same issue.
It will be great help to have an API to get call record ids/call records for a specific user OR an API which can accept date range to return all call records details for that time period like we have for List Direct Routing call as below:
GET https://graph.microsoft.com/v1.0/communications/callRecords/getDirectRoutingCalls(fromDateTime=2019-11-01,toDateTime=2019-12-01)
