    A Mechanism for Transporting User-to-User Call Control Information                                  in SIP

Abstract

   There is a class of applications that benefit from using SIP to    exchange User-to-User Information (UUI) data during session    establishment.  This information, known as call control UUI data, is    a small piece of data inserted by an application initiating the    session and utilized by an application accepting the session.  The    syntax and semantics for the UUI data used by a specific application    are defined by a UUI package.  This UUI data is opaque to SIP and its    function is unrelated to any basic SIP function.  This document    defines a new SIP header field, User-to-User, to transport UUI data,    along with an extension mechanism.
