The current ORTC API document does not define capabilities and settings for DTMF (RFC 4733). This should be added to Section 9.3.2.

Useful properties would include ptime as well as the DTMF Named Events supported (e.g. 0-15).

Proposed solution is to add a section DTMF

The following capabilities are defined for DTMF, as noted in [RFC4733] Section 2.4:

Property Name Values Notes
events DOMString An indication of what telephony events are supported (or configured). Events are listed as one or more comma-separated elements. Each element can be either a single integer providing the value of an event code or an integer followed by a hyphen and a larger integer, presenting a range of consecutive event code values. The list does not have to be sorted. No white space is allowed in the argument. The union of all of the individual event codes and event code ranges designates the complete set of event numbers supported by the implementation.

Slight update to the text: change "capabilities" to "capabilities and settings".
