- After answer the call in the callbacks API :

```
if (parsedEvent is CallConnected callConnected) {
var welcomePlaySource = new TextSource(WelcomeMessage2)
{
VoiceName = "en-US-NancyNeural"
};
await callMedia.PlayToAllAsync(welcomePlaySource);
}
```
- The sound not played and the callback event after PlayToAllAsync is PlayCompleted without any error.

- There is issue too appear when DMTF Recognize the event callback is RecognizeFailed and the error is silence time out after 10 seconds.
```
var recognizeOptions = GetMediaRecognizeChoiceOptions(MainMenu, targetPhonenumber);
await callMedia.StartRecognizingAsync(recognizeOptions);

CallMediaRecognizeChoiceOptions GetMediaRecognizeChoiceOptions(string content, string targetParticipant, string context = "")
{
var playSource = new TextSource(content) { VoiceName = SpeechToTextVoice };

var recognizeOptions =
new CallMediaRecognizeChoiceOptions(targetParticipant: new PhoneNumberIdentifier(targetParticipant), GetChoices())
{
InterruptCallMediaOperation = false,
InterruptPrompt = false,
InitialSilenceTimeout = TimeSpan.FromSeconds(10),
Prompt = playSource,
OperationContext = context
};

return recognizeOptions;
}

List GetChoices()
{
return new List {
new RecognitionChoice("Confirm", new List {
"Confirm",

}) {
Tone = DtmfTone.One
},
new RecognitionChoice("Cancel", new List {
