Обработка ошибок iOS SDK

При получении статуса потока kFPWCSStreamStatusFailed, метод FPWCSApi2Stream.getStatusInfo возвращает код возникшей ошибки, который может быть преобразован в текстовое описание при помощи метода streamStatusToString. Аналогичным образом обрабатываются и ошибки при совершении звонка.
