+short-title: createDTMFSender()
+slug: Web/API/RTCPeerConnection/createDTMFSender
+page-type: web-api-instance-method
+status:
+  - deprecated

+browser-compat: api.RTCPeerConnection.createDTMFSender
+---
+
+{{APIRef("WebRTC")}}{{Deprecated_Header}}{{non-standard_header}}
+
+The **`createDTMFSender()`** method of the {{domxref("RTCPeerConnection")}} interface creates a new {{domxref("RTCDTMFSender")}} object associated with the specified {{domxref("MediaStreamTrack")}}, which can be used to send DTMF tones over the connection.
+
+This method is deprecated and should not be used. Instead, use the {{domxref("RTCRtpSender.dtmf")}} property to access the DTMF sender associated with a specific sender.
+
+## Syntax
+
+```js-nolint
+createDTMFSender(track)
+```
+
+### Parameters
+
+- `track`
+  - : A {{domxref("MediaStreamTrack")}} object representing the track to associate with the new DTMF sender.
+
+### Return value
+
+A new {{domxref("RTCDTMFSender")}} object.
+
+## Examples
+
+This example creates a new DTMF sender associated with the specified track.
+
+```js
+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 {{domxref("RTCRtpSender.dtmf")}} property:
+
+```js
+navigator.getUserMedia({ audio: true }, (stream) => {
+  const pc = new RTCPeerConnection();
+  const track = stream.getAudioTracks()[0];
+  const sender = pc.addTrack(track, stream);
+  const dtmfSender = sender.dtmf;
+});
+```
+
