Technical Summary:

    Opportunistic Secure Real-time Transport Protocol (OSRTP) is an
    implementation of the Opportunistic Security mechanism, as defined
    in RFC 7435, applied to Real-time Transport Protocol (RTP).  OSRTP
    allows encrypted media to be used in environments where support
    for encryption is not known in advance, and not required.  OSRTP
    does not require SDP extensions or features and is fully backwards
    compatible with existing implementations using encrypted and
    authenticated media and implementations that do not encrypt or
    authenticate media packets.  OSRTP is not specific to any key
    management technique for SRTP.  OSRTP is a transitional approach
    useful for migrating existing deployments of real-time
    communications to a fully encrypted and authenticated state.

Working Group Summary:

    There is consensus in the WG around this document.
