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
rules which apply for a certain 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.
