This document defines a standard mechanism for capturing the history
information associated with a Session Initiation Protocol (SIP)
request. This capability enables many enhanced services by providing
the information as to how and why a SIP request arrives at a specific
application or user. This document defines an optional SIP header
field, History-Info, for capturing the history information in
requests. The document also defines SIP header field parameters for
the History-Info and Contact header fields to tag the method by which
the target of a request is determined. In addition, this
specification defines a value for the Privacy header field that
directs the anonymization of values in the History-Info header field.
This document obsoletes RFC 4244.
This document is a product of the Session Initiation Protocol Core Working Group of the IETF.
This is now a Proposed Standard.
