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, is a small piece of data
inserted by an application initiating the session, and utilized by an
application accepting the session. 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, along
with an extension mechanism.
