I have tried to call the API with diferent dates and can't get it to return data:
https://graph.microsoft.com/beta/communications/callRecords/getPstnCalls(fromDateTime=2021-08-01,toDateTime=2021-08-09)
I always get
{
"@odata.context": "https://graph.microsoft.com/beta/$metadata#Collection(microsoft.graph.callRecords.pstnCallLogRow)",
"@odata.count": 0,
"value": []
}
Do we need some other permission?
