RTCPeerConnection: createDTMFSender() method
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The createDTMFSender()
method of the RTCPeerConnection
interface creates a new RTCDTMFSender
object associated with the specified MediaStreamTrack
, which can be used to send DTMF tones over the connection.
This method is deprecated and should not be used. Instead, use the RTCRtpSender.dtmf
property to access the DTMF sender associated with a specific sender.
Syntax
createDTMFSender(track)
Parameters
track
-
A
MediaStreamTrack
object representing the track to associate with the new DTMF sender.
Return value
A new RTCDTMFSender
object.
Examples
This example creates a new DTMF sender associated with the specified track.
navigator.getUserMedia({ audio: true }, (stream) => {
const pc = new RTCPeerConnection();
const track = stream.getAudioTracks()[0];
const dtmfSender = pc.createDTMFSender(track);
});
This could be rewritten using the RTCRtpSender.dtmf
property:
navigator.getUserMedia({ audio: true }, (stream) => {
const pc = new RTCPeerConnection();
const track = stream.getAudioTracks()[0];
const sender = pc.addTrack(track, stream);
const dtmfSender = sender.dtmf;
});
