当用户在按键事件中选择井号"#"时,Twilio只是断开/挂断呼叫.

   response = Twilio::TwiML::Response.new do |r|
      r.Gather action: post_to do
      r.Play TWILIO["RECORDINGS_URL"] + "recording.wav"
      r.Say "We have recieved no input. Thank you."
      end
      r.Hangup
    end

在这种情况下,当用户在播放录音时选择#键时,Twilio会跳到r.Say的下一个名字并挂断电话.并且事件不会触发到选定数字为"#"的应用程序服务器.

当用户选择"#"以外的选项,即0-9或*时,它可以正常工作.
