This draft is a work item of the Session Initiation Protocol Working Group of the IETF.

        Title           : Rejecting Anonymous Requests in the Session Initiation Protocol (SIP)
        Author(s)       : J. Rosenberg
        Filename        : draft-ietf-sip-acr-code-05.txt

The Session Initiation Protocol (SIP) allows for users to make
anonymous calls.  However, users receiving such calls have the right
to reject them because they are anonymous.  SIP has no way to
indicate to the caller that the reason for call rejection was that
the call was anonymous.  Such an indication is useful to allow the
call to be retried without anonymity.  This specification defines a
new SIP response code for this purpose.

NOTE:   The mail server at ietf.org can return the document in
        MIME-encoded form by using the "mpack" utility.  To use this
        feature, insert the command "ENCODING mime" before the "FILE"
        command.  To decode the response(s), you will need "munpack" or
        a MIME-compliant mail reader.  Different MIME-compliant mail readers
        exhibit different behavior, especially when dealing with
        "multipart" MIME messages (i.e. documents which have been split
        up into multiple messages), so check your local documentation on
        how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
