Title : A Mechanism for Transporting User to User Call Control Information in SIP

Abstract:
There is a class of applications which 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.
