Welcome to the RingCentral Community

This PHP sample code should help you read call log and download the call recording if any.

<?php
require('vendor/autoload.php');

$RINGCENTRAL_CLIENTID = "You-App-ClientId";
$RINGCENTRAL_CLIENTSECRET = "You-App-ClientSecret";
$RINGCENTRAL_SERVER = 'https://platform.ringcentral.com';

$RINGCENTRAL_USERNAME = "username";
$RINGCENTRAL_PASSWORD = "passaword";
$RINGCENTRAL_EXTENSION = "extension-number";

$rcsdk = new RingCentral\SDK\SDK($RINGCENTRAL_CLIENTID, $RINGCENTRAL_CLIENTSECRET, $RINGCENTRAL_SERVER);

$platform = $rcsdk->platform();
try{
  $platform->login($RINGCENTRAL_USERNAME, $RINGCENTRAL_EXTENSION, $RINGCENTRAL_PASSWORD);
  $params = array(
      'dateFrom' => '2022-03-01T23:59:59.999Z',
      'dateTo' => '2022-03-31T23:59:59.999Z'
      );
  $resp = $platform->get('/account/~/extension/~/call-log', $params);
  foreach ($resp->json()->records as $record) {
      if ($record->type == "Voice"){
        if (isset($record->recording)){
          $parts = explode('/', $record->recording->uri);
          $fileName = $parts[count($parts)-1].".mp3";
          download_callrecording_content($record->recording->contentUri, $fileName);
        }
      }
  }
}catch (\RingCentral\SDK\Http\ApiException $e) {
      print 'Expected HTTP Error: ' . $e->getMessage() . PHP_EOL;
}

function download_callrecording_content($contentUri, $fileName){
    global $platform;
    echo ("Save call recording file to the local machine.\n");
    $uri = $platform->createUrl($contentUri, array(
          'addServer' => false,
          'addMethod' => 'GET',
          'addToken'  => true
    ));
    file_put_contents($fileName, fopen($uri, 'r'));
}
