Licence: Teams Phone with Calling Plans, Operator Connect or Direct Routing.

Endpoints: GET /v1.0/communications/callRecords/getPstnCalls(fromDateTime,toDateTime) · GET /v1.0/communications/callRecords/getDirectRoutingCalls(fromDateTime,toDateTime)

If a permission is missing, this report shows a red load error with the Graph status code — not an empty table.
