The read-only dtmf property on the
RTCRtpSender interface returns a
RTCDTMFSender object which can be used to send DTMF tones
over the RTCPeerConnection . See Using DTMF for details on how to
make use of the returned RTCDTMFSender object.
Syntax
var dtmfSender = RTCRtpSender.dtmf;Value
An RTCDTMFSender which can be used to send DTMF over the RTP session, or
null if the track being carried by the RTP session or the
RTCPeerConnection as a whole doesn't support DTMF.
Only audio tracks can support DTMF, and typically only one audio track per
RTCPeerConnection will have an associated RTCDTMFSender
