title: Issue with Twilio restarting the VoiceResponse
body: <p>I am using the Tiwlio SDK to create a CallResource:</p>
  
  <pre><code>Dim tCall = CallResource.Create(toPhone,
                                          fromPhone,
                                          url:=New Uri("http://blah.com/api-callback")
                                          )
  </code></pre>
  
  <p>The Callback returns twiml.  Once it is done recording, it never hits the Thank you section, instead starts over with the first Say.  </p>
  
  <pre><code>Dim vr As New Twilio.TwiML.VoiceResponse()
          vr.Pause(1)
          vr.Say("Hello, please talk after the beep.", voice:="woman")
          vr.Record(trim:="trim-silence", maxLength:=10, recordingStatusCallback:=New Uri("http://blah.com/api-complete"))
          vr.Pause(10)
          vr.Say("Thank you for registering.", voice:="woman")
          vr.Hangup()
  </code></pre>
  
  <p>Any ideas?</p>
