There is a need for applications 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. Applications define a UUI package
for the transport of their UUI data. This 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.
