This is a twilio app that I put together to help troubleshoot a DTMF issue from a phone system.
It's purpose is to echo back the number keys that you entered when prompted. This can assist you in determining if your land line/cellphone/VOIP phone is sending the signals that you think it is/should.
$ pip install flask
$ pip install lxml
