不允许来电Lync Api或为来电禁用声音

Question

I have developed a windows application using Lync api. My client want to disable incoming calls to this application. So i have added some thing like this. I am able to cut the call but there are few rings before im able to do that

private void ClientInitialized(IAsyncResult result)
        {
            try
            {
                //registers for conversation related events
                //these events will occur when new conversations are created (incoming/outgoing) and removed
                client.ConversationManager.ConversationAdded += ConversationManager_ConversationAdded;
                client.ConversationManager.ConversationRemoved += ConversationManager_ConversationRemoved;
            }
            catch (Exception ex)
            {
                MessageBox.Show("Problem in adding/removing conversation", "Bella IVIS", MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
        }

void ConversationManager_ConversationAdded(object sender, ConversationManagerEventArgs e)
        {
     try
     {    
     var _client = client;
     if (e.Conversation.State == ConversationState.Active)
     {
     for (int intLoop = 0; intLoop < _client.ConversationManager.Conversations.Count; intLoop++)
     {
         _client.ConversationManager.Conversations[intLoop].End();
     }
     _client = null;
      return;
     }
    }
  }

I do not know if there is a way to capture conversation before Conversation_Added event. However, if the Lync status is not of any relevance to you then you change the Lync Status to "Do not disturb". This way you would never get any incoming request (unless the user Lync setting allow to do so)

var newInformation =new Dictionary<PublishableContactInformationType, object>();
        newInformation.Add(PublishableContactInformationType.Availability, ContactAvailability.DoNotDisturb);

try
{
     this.lyncClient.Self.BeginPublishContactInformation(newInformation,(result) => this.lyncClient.Self.EndPublishContactInformation(result) , null);
}  catch {}
