title: Make a telephone call and send different DTMF tones during the call in iOS
body: <p>Is it possible to call a phone number programmatically in iOS and send different DTMF tones during the call?.
  Basically I want an App to handle the IVR call. I don't know anything about iOS programming. I just want to know the feasibility so that I will put further effort.
  Thanks</p>
