我目前有一個問題，即錄音少數是空的（從Twilio的服務器上下載它們時）時，他們應該不會摔跤。Twilio - 下載通話錄音有時是空
我的應用程序目前負責每天約10,000個電話。這些呼叫中的每一個，如果被回答，都會被記錄下來，然後下載到我的服務器上。
無論出於何種原因，這些下載的MP3文件少數是空的，它們的大小坐在363個字節（無音頻，只需將文件本身），即使我知道應該有MP3文件的內容。例如，某些電話會持續30-40分鐘，但下載時會有空的錄音。
我在PHP開發和已連接的代碼被用於下載下面的記錄。有沒有看起來像偶爾會引起問題？我嘗試尋找其他人可能遇到的類似問題，至今還沒有發現任何問題。
請記住這個代碼適用的情況下，90％......它只是不正確地下載這些10％。
非常感謝您的時間！
