This bug will track the details of the DTMF API.

Current proposal (from https://docs.google.com/a/google.com/document/d/1oqPfWoeq9mDAJKV8RStw-FVzln7HRO50gkFR0wiPjbk/edit?hl=en_US):

class AudioMediaStreamTrack : MediaStreamTrack { readonly attribute boolean canInsertDTMF; void insertDTMF(in DOMString tones, optional long duration) }

• |tones| consists of 0-9, '#', '*', A-D, and ','
• if unspecified, |duration| is 100 ms
• inter-digit pause is 50 ms
• ',' adds an additional 50 ms pause
