Re: [webrtc-extensions] Enabling opus discontinuous transmission(DTX) without SDP munging (#120)

> Note that he "SDP munging" is _not_ the bad variant between createOffer/createAnswer and SLD as dtx is controlled by the remote description.

thanks reply, as far as I know, dtx is an encoder behavior.  a call with SFU scenario may like this:

client A (audio sender)<-----> SFU<------> client B(audio decoder)
client A exchange offer/answer with SFU,  the sdp answer from SFU control dtx ability but not client B.

ortc seems add this to [rtcrtpencodingparameters](https://w3c.github.io/webrtc-pc/#rtcrtpencodingparameters)(https://draft.ortc.org/#dom-rtcrtpencodingparameters)
