I’m not sure you’ll be able to hear them in the audio, as they’re sent as a separate payload type (RFC 4733) and not encoded in the audio stream.

I suggest to read this MDN article and it might get much clearer:

> **[Using DTMF with WebRTC - Web APIs | MDN](https://developer.mozilla.org/en-US/docs/Web/API/WebRTC_API/Using_DTMF)**
>
> In order to more fully support audio/video conferencing, WebRTC supports sending DTMF to the remote peer on an RTCPeerConnection. This article offers a brief high-level overview of how DTMF works over WebRTC, then provides a guide for everyday...
