Title : Transporting User to User Call Control Information in SIP for ISDN Interworking

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 extension will also be used for native SIP endpoints
implementing similar services and interworking with ISDN services.
This document discusses requirements and approaches and recommends a
new header field be standardized. Example use cases include an
exchange between two user agents, retargeting by a proxy, and
redirection. An example application is in an Automatic Call
Distributor (ACD) in a contact center.
