This document introduces the transport of call control related 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 ISDN UUI Service, this extension
will also be used for native SIP endpoints requiring application UUI.
