RTCRtpSender: dtmf property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
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
