Title : Interworking ISDN Call Control User Information with SIP

Abstract:
The motivation and use cases for interworking and transporting ITU-T
DSS1 User-user information element data in SIP are described in RFC
6567. 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 defines a usage (a new package) of the
User-to-User header field to enable interworking with this ISDN
service.
This document covers the interworking with both public ISDN and
private ISDN capabilities, so the potential interworking with QSIG
will also be addressed.
The package is identified by a new value "isdn-uui" of the "purpose"
header field parameter.
