    Description of Working Group:

    The Session Initiation Protocol Project INvestiGation (SIPPING)
    working group is chartered to document the use of SIP for several
    applications related to telephony and multimedia, and to develop
    requirements for extensions to SIP needed for those applications.
    Such requirements will be referred to the SIP working group for
    development of any new SIP method, header, or option-tag as described
    in Change Policy for SIP (RFC 3467).

    Guiding principles for the performance of SIPPING's work will include:

    1. Documenting the requirements of specific chartered tasks.

    2. Documenting the usage of SIP to solve real problems that need
    to be solved in a standardized way. Examples of important
    topics identified are the session policy architecture, allowing
    network entities to convey policy into an User Agent's
    activity; requirements analysis for session border
    controllers to determine how best such devices can
    operate with SIP usage; guidance on IPv4-IPv6
    co-existence support by SIP and SIP-supported media; and
    inclusion of real-time text conversation (ToIP), service
    invocations benefitting hearing and speech impaired users,
    and other SIP equal access services as requirements are proposed.

    3. Looking for commonalities among the chartered tasks and ongoing
    SIP-related development, as commonalities may indicate for general,
    reusable functionality in SIP.

    4. Describing the requirements for any extension determined to pass
    there hurdles, and handing the development task to the SIP WG.

    5. Developing procedures and requirements for configuration and
    delivery of SIP User Profiles

    Besides performing needed specification of several applications
    of SIP, SIPPING can be seen as also working out use cases that
    clarify the role of SIP in the Internet, and help to ensure that
    Occam's razor is appropriately applied to SIP usage.

    The security of all the deliverables will be of special importance.
    The technology for security will be keyed from the SIP Security
    specification within RFC 3261, and additional SIP specifications
    as they apply.
