Sounding like an Ogg player on 'repeat':

In a single server scenario, we don't need a standard way to ask for
DTMF generation between RTCWEB client and server. An RTCWEB server
that includes a PSTN gateway function could use H.248's DTMF
generation package to tell the media gateway that it should insert
tones.

A more disruptive way to do DTMF would be an API function wich lets
the JS application insert arbitrary sound bits into the media stream.
A JS client could locally generate DTMF samples and play them. But of
course this would need to be discussed on the W3C list.
