Instructions / contact To generate tones, either press the on-screen buttons live (after pressing the striped "GO!" button first of all), or enter a sequence of numbers / letters into the "Sequence to convert" box. A single DTMF tone (which are usually sounded in pairs) can be entered using a lower-case letter. A pause (in lieu of a tone) can be entered with "p".
