Skype for Business 拨出电话和播放音频文件

Question

目标是为模块开发系统监控解决方案的接口，该模块调用值班人员并从文件系统播放一些语音/音频文件。

我有一个启用了电话选项的 Skype for business 2015（以前的 lync）用户。我也可以拨打电话号码。但接下来的问题是，如何等到被叫方接听电话并播放音频文件（或者更好的是 System.Speech 变体而不是播放音频文件），然后该人必须批准他/她接到电话。

我目前拥有的：

public void SendLyncCall(string numberToCall, string textToSpeech)
{
  var targetContactUris = new List<string> {numberToCall}; //"tel:+4900000000" }; //removed here

  _automation.BeginStartConversation(AutomationModalities.Audio, targetContactUris, null, StartConversationCallback, null);

    while (this.globalConv == null)
    {
      Thread.Sleep(1);
    }
  if (globalConv != null)
  {
    LyncClient client = LyncClient.GetClient();

    client.DeviceManager.EndPlayAudioFile(
      client.DeviceManager.BeginPlayAudioFile(@"d:\tmp\test1.wav",
        AudioPlayBackModes.Communication,
        false,
        null,
        null));
  }
}

private void StartConversationCallback(IAsyncResult asyncop)
{
 // this is called once the dialing completes..
if (asyncop.IsCompleted == true)
{

    ConversationWindow newConversationWindow = _automation.EndStartConversation(asyncop);
  globalConv = newConversationWindow;
    AVModality avModality = globalConv.Conversation.Modalities[ModalityTypes.AudioVideo] as AVModality;


    foreach (char c in "SOS")
    {
      avModality.AudioChannel.BeginSendDtmf(c.ToString(), null, null);
      System.Threading.Thread.Sleep(300);
    }

  }
}

另一个问题是，是否可以将整个模块更改为可以作为 Windows 服务运行的注册端点？目前我的 sfb 必须打开并登录..

Answer 1

请注意，这不是您发布的UCMA 代码，而是Lync Client SDK 代码。

我假设您想知道如何使用 Lync 客户端 SDK 执行您所要求的操作。

您需要挂钩AVModality.ModalityStateChanged 事件以查看它何时更改为 AVModality.State 更改为Connected。

一旦处于已连接状态，您就可以为所欲为。

调整我想出的代码：

private void StartConversationCallback(IAsyncResult asyncop)
{
    // this is called once the dialing completes..
    if (asyncop.IsCompleted == true)
    {
        ConversationWindow newConversationWindow = _automation.EndStartConversation(asyncop);
        AVModality avModality = newConversationWindow.Conversation.Modalities[ModalityTypes.AudioVideo] as AVModality;
        avModality.ModalityStateChanged += ConversationModalityStateChangedCallback;
    }
}

private void ConversationModalityStateChangedCallback(object sender, ModalityStateChangedEventArgs e)
{
    AVModality avModality = sender as AVModality;
    if (avModality != null)
    {
        switch (e.NewState)
        {
            case ModalityState.Disconnected:
                avModality.ModalityStateChanged -= ConversationModalityStateChangedCallback;
                break;

            case ModalityState.Connected:
                avModality.ModalityStateChanged -= ConversationModalityStateChangedCallback;
                foreach (char c in "SOS")
                {
                    avModality.AudioChannel.BeginSendDtmf(c.ToString(), null, null);
                    System.Threading.Thread.Sleep(300);
                }
                break;
        }
    }
}
