RTCRtpSender: dtmf property
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.
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.
Note: Only audio tracks can support DTMF, and typically only one audio track per
RTCPeerConnection will have an associated RTCDTMFSender
