Title: An Extension to the Session Initiation Protocol for Request History Information
State: Active
Authors: Mary Barnes
Group: Session Initiation Protocol (sip)
Date: 2004-12-07
This draft defines a standard mechanism for capturing the history
information associated with a SIP request. This capability enables many
enhanced services by providing the information as to how and why a call
arrives at a specific application or user. This draft defines a new
optional SIP header, History-Info, for capturing the history information in
requests. A new option tag, Histinfo, to be included in the Supported
header, is defined to allow UAs to indicate whether the History-Info should
be returned in responses to a request which has captured the history
information. A new priv-value, history, is added to the Privacy header to
allow for privacy handling of the History-Info header.
