title: Microsoft Bot Framework start the conversation from specific waterfall step in dialog
body: <p>Microsoft Bot Framework V4, I have a waterfall Dialog defined in a dialog as below</p>
  
  <pre><code>var waterfallSteps = new WaterfallStep[]
  
          {
              CallConfirmAsync,
              SimilarProductAsync,
              CheckNewVersionAsync,
          };
  
          AddDialog(new WaterfallDialog("productenquiry", waterfallSteps));
  </code></pre>
  
  <p>After the execution of the first two waterfall steps, my conversation is stop due to unresponsiveness from user's end. So I want to resume from the third method when i.e., CheckNewVersionAsync when the user comes back again to the bot.</p>
  
  <p>Can anyone please help me here.</p>
