7.2. insertDTMF
The tones parameter is treated as a series of characters.
The characters 0 through 9, A through D, #, and * generate the associated
DTMF tones.
The characters a to d MUST be normalized to uppercase on entry and are
equivalent to A to D.
As noted in [RTCWEB-AUDIO] Section 3, support for the characters 0 through 9,
A through D, #, and * are required.
The character ',' MUST be supported, and indicates a delay of 2 seconds
before processing the next character in the tones parameter.
All other characters (and only those other characters) MUST be considered
unrecognized.
