Thank you Eduardo, Josť and Zoltan for drafting telephony APIs at [1]

I was going through the draft version and had couple of questions noted below.

1. Support of video call.
Does supporting of video call comes within the scope of the above
draft telephony APIs? Now that there exist media capture API
getUserMedia etc ([2] although a draft version) I was wondering if
this should be handled by the telephony APIs? Or do you think that it
might conflict with WebRTC specification for the video calling purpose

2. Supporting of receiving and decoding the DTMF tones
The telephony API in above draft specifies the sendTone() API for
sending DTMF tones over the wire. Similarly is there a possibility of
having receiveTone() or equivalent API for receiving and decoding the
DTMF tones received from the call originator. There exist some
reference library for android which has similar feature (though [4] is
not a officially available library, I guess its a third party

These are just my thoughts. Please let me know your feedback/comments
on the above.

Thank you,
Vivek Galatage
