Working with voicemail messages in the sandbox account. I can see the two voicemails I left. I realized for the first one I didn't have transcription turned on for the account. But now on the second voicemail record the vmTranscriptionStatus shows "failed"

Is that normal behavior in the sandbox?

ListMessagesParameters parameters = new ListMessagesParameters();

            parameters.messageType = new StringS] {"VoiceMail"};

            //var resp = await restClient.Restapi().Account().Extension().List();

            var response = await restClient.Restapi().Account().Extension().MessageStore().List(parameters);

            foreach ( GetMessageInfoResponse record in response.records)

            {

                if (record.attachments != null)

                {

                    foreach (var attachment in record.attachments)

                    {

                        var fileName = "./src/test/resources/" + record.attachmentsÂ0].id + "_voicemail.txt";

                        if (attachment.type == "AudioTranscription")

                        {

                            var res = restClient.Restapi().Account().Extension().MessageStore(record.id.ToString()).Content(attachment.id.ToString()).Get();

                            //Path path = Paths.get(fileName);

                            //Files.write(path, res);

                        }

                    }

                }

            }

}
