>From the text -- -- The following four labels are defined for use in ALPN: webrtc The DTLS session is used to establish keys for a Secure Real- time Transport Protocol (SRTP) - known as DTLS-SRTP - as described in [RFC5764]. The DTLS record layer is used for WebRTC data channels [I-D.ietf-rtcweb-data-channel]. c-webrtc The DTLS session is used for confidential WebRTC communications, where peers agree to maintain the confidentiality of the communications, as described in Section 3. A more thorough definition of what WebRTC communications entail is included in [I-D.ietf-rtcweb-transports]. -- I see only two labels there.
