Twilio浏览器调用在POST中发送错误的调用Sid

我设置了浏览器调用，并在我的TwiML应用程序中设置了状态回调url。Twilio以以下格式发布状态

array (
  'ApiVersion' => '2010-04-01',
  'Called' => NULL,
  'CallStatus' => 'completed',
  'Duration' => '1',
  'From' => 'client:browser',
  'CallDuration' => '13',
  'Direction' => 'inbound',
  'Timestamp' => 'Mon, 16 Apr 2018 19:35:26 +0000',
  'AccountSid' => 'asdasdasdadasdasdasdasdasdasdas',
  'CallbackSource' => 'call-progress-events',
  'ApplicationSid' => 'rwerwerwerwewewewewwrwe',
  'Caller' => 'client:browser',
  'SequenceNumber' => '0',
  'To' => NULL,
  'CallSid' => 'CA9c6408108969fsf6f1c53396003d931',
)  

我正在设法得到电话，从和其他细节。是的，是的

$callsid = $_POST['CallSid'];
$call = $client->calls($callsid)->fetch();

但每次都失败了。当我检查仪表板上的CallSod时，它与他们在webhook中发送的内容不同

我有什么遗漏吗？

解决了。我需要让孩子打电话给SID来获取信息

$call = $client->calls->read(
    array("ParentCallSid" => $callsid )
);
