• Answer a call and use Text-to-speech (TTS) to say a message to the caller:

  CallState state = channel.Answer();
  if (state == CallState.Answered)
  {
  	channel.FilePlayer.Say("Hello. Thank you for calling.");
  }

  Play a media file, allowing the caller to press a key to interrupt:

  FilePlayerCause playCause = channel.FilePlayer.Play("welcome.wav", true);
  if (FilePlayerCause.BargeIn == playCause)
  {
  	this.Trace.TraceInfo("Playback was interrupted by a keypress");
  }

  Record a message from the caller, allowing the caller to press a key to end the recording:

  string recordFileName = "recordedMessages/MessageFrom" + channel.CallDetails.CallFrom + ".wav";
  channel.FileRecorder.Start(recordFileName, true);
  
  // Play a tone to signal that recording has started
  channel.DtmfPlayer.Play("0");
  
  channel.FileRecorder.WaitUntilFinished(60);

• Answer a call and use Text-to-speech (TTS) to say a message to the caller:

  state = channel.answer()
  if state == channel.State.ANSWERED:
  	cause = channel.FilePlayer.say("Hello. Thank you for calling.")

  Play a media file, allowing the caller to press a key to interrupt:

  cause = channel.FilePlayer.play("welcome.wav", barge_in=True)
  if cause == channel.FilePlayer.Cause.BARGEIN:
  	my_log.info("Playback was interrupted by a keypress")

  Record a message from the caller, allowing the caller to press a key to end the recording:

  record_file_name = "recorded_messages/message_from_{0}.wav".format(channel.Details.call_from)
  channel.FileRecorder.start(record_file_name, barge_in=True)
  
  # Play a tone to signal that recording has started
  channel.DTMFPlayer.play('0')
  
  channel.FileRecorder.wait_until_finished(seconds_timeout=60)

  Record a message from the caller, allowing the caller to press a key to end the recording:
