    Description of Working Group:

          ftp://standards.nortelnetworks.com/megaco/docs/

    The Megaco media gateway control protocol, RFC 3015 (also published as
    ITU-T Recommendation H.248), was developed by the Megaco Working Group
    in close cooperation with ITU-T Study Group 16. The protocol responds
    to the requirements documented in RFC 2805.

    The Megaco Working Group has identified a large number of corrections
    to the protocol specification in the year and a half since RFC
    3015/Rec.
    H.248 was approved. As guardians of the protocol specification, Study
    Group 16 maintains a record of these corrections in the form of an
    "Implementor's Guide". Study Group 16 now proposes to issue a new
    version of Recommendation H.248 incorporating these corrections and a
    limited number of new protocol features. The current charter includes
    one package, on naming patterns. If the WG determines that other
    packages are of general usefulness, an AD and IESG review is needed to
    permit addition of the package to the charter.

    The basic mandate of the Megaco Working Group is to cooperate with the
    ITU-T in the continuing refinement and evolution of the Megaco/H.248
    protocol. This specifically includes participation in the development
    of H.248v2 and subsequent versions, creation of packages of general
    usefulness to users of the protocol, and creation of documents
    providing additional information to the development community on
    specific aspects of the protocol.

    The work of package development for specific applications is
    specifically excluded from the Working Group's mandate. However, the
    Megaco list will continue to be a place where such packages can be
    discussed and refined before being submitted to the IESG for potential
    publication as individually-submitted RFCs.
