Extract Data from Ads Report to Spreadsheet

Hi I am trying to write a script that will extract the data from Google Ads Report (Call Details) or 'call_metrics_call_details_report' to a spreadsheet automatically. I have been able to extract all the details successfully - except for the caller phone number. There also does not seem to be a google attribute for this. Can anybody help? Thank you

function importCallDetails() {   var accountId = AdWordsApp.currentAccount().getCustomerId();   var startDate = "INSERT_START_DATE_HERE";   var endDate = "INSERT_END_DATE_HERE";   var query = "SELECT CallStartTime, CallDuration, CallerCountryCallingCode, CampaignName,     CampaignId " + "FROM CALL_METRICS_CALL_DETAILS_REPORT";   var report = AdsApp.report(query);   var data = report.rows();   var spreadsheetUrl = 'https://docs.google.com/spreadsheets/*********/';   var spreadsheet = SpreadsheetApp.openByUrl(spreadsheetUrl);   var ss = spreadsheet.getSheetByName('PAGE1');   ss.clearContents();   report.exportToSheet(ss); }   function main() {   importCallDetails(); }
