> The only place DTMF support is mentioned in JSEP is when setting remote description with m= section having telephone-event lines. Does this means under that condition we can expect sender.dtmf to be set?

I think that was the intention. We talked about RTCDTMFSender in the last virtual interim, and this was briefly brought up.

However... what happens if you apply another remote description that removes the "telephone-event" format? Does `dtmf` become null again? What happens if the application holds onto the `RTCDTMFSender` object and tries to call `insertDtmf` in this state? I think we still need to answer those questions.
