Several approaches to transporting the ITU-T Q.931 User to User
Information Element (UU IE) data in SIP have been proposed. 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. This 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.
