RTCRtpSender.dtmf

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.

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