         Interworking ISDN Call Control User Information with SIP

Abstract

   The motivation and use cases for interworking and transporting User-    to-User Information (UUI) from the ITU-T Digital Subscriber    Signalling System No. 1 (DSS1) User-user information element within    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 have the ability to interwork    with this ISDN service for end-to-end transparency.  This document    defines a usage (a new package called the ISDN UUI package) of the    User-to-User header field to enable interworking with this ISDN    service.

   This document covers interworking with both public ISDN and private    ISDN capabilities, so the potential interworking with QSIG will also    be addressed.

   The package is identified by the new value "isdn-uui" of the    "purpose" header field parameter.
