What specific section or headline is this issue about?

Examples

What information was incorrect, unhelpful, or incomplete?

Method getParameters() specified in the Examples section does not exist.

What did you expect to see?

I expected to find a method allowing me to compare usernameFragment between incoming ICE candidates and existing RTCPeerConnection.

Do you have any supporting links, references, or citations?

None

Do you have anything more you want to share?

It is possible to get around this issue by reading the sdp of remoteDescription directly and using regular expressions. Connection in the given example refers to an instance of a RTCPeerConnection. Result usernameFragment is equal to usernameFragment for the RTCPeerConnection and it can be compared with incoming ICE candidates' usernameFragment.

           const sdp = connection.remoteDescription?.sdp;

            if ( sdp ) {
                const iceUfragRegex = /a=ice-ufrag:(.+)\r?\n/;
                const match = sdp.match(iceUfragRegex);
                const usernameFragment = match ? match[1] : null;
            }

RTCRtpReceiver objects do have a getParameters() method — https://developer.mozilla.org/en-US/docs/Web/API/RTCRtpReceiver/getParameters — but the RTCDtlsTransport object returned from receiver.transport doesn’t.
