You can choose between several tabs which makes it easy to see exactly the call details you are looking for. 'All Calls' is an overview of all calls including the date, caller and callee number, status, time and cost. 'Recordings' and 'Transcriptions' is where you can find all calls which you recorded or transcribed via Flow Builder or API. 'Logs' is a list of all call logs for detailed info on call data.
