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.
A common example in another protocol is the ISDN User to User
Information Service. As networks move to SIP it is important that
applications requiring this data can continue to function in SIP
networks as well as the ability to interwork with this ISDN service
for end-to-end transparency. This document discusses requirements
and approaches to achieve this. In addition, the extension will also
be used for native SIP endpoints implementing similar services and
interworking with ISDN services. Example use cases include an
exchange between two user agents, retargeting by a proxy, and
redirection. An example application is an Automatic Call Distributor
(ACD) in a contact center.
