This document introduces the transport of call control User-to-User
Information (UUI) using the Session Initiation Protocol (SIP) and
develops several requirements for a new SIP mechanism.  Some SIP
sessions are established by or related to a non-SIP application.
This application may have information that needs to be transported
between the SIP User Agents during session establishment.  In
addition to interworking with the Integrated Services Digital Network
(ISDN) UUI Service, this extension will also be used for native SIP
endpoints requiring application UUI.  This document is not an Internet 
Standards Track specification; it is published for informational purposes.

This document is a product of the Call Control UUI Service for SIP Working Group of the IETF.
