           Modern Problem Statement, Use Cases, and Framework
               draft-ietf-modern-problem-framework-04.txt

Abstract

   The functions of the public switched telephone network (PSTN) are
   rapidly migrating to the Internet.  This is generating new
   requirements for many traditional elements of the PSTN, including
   telephone numbers (TNs).  TNs no longer serve simply as telephone
   routing addresses: they are now identifiers which may be used by
   Internet-based services for a variety of purposes including session
   establishment, identity verification, and service enablement.  This
   problem statement examines how the existing tools for allocating and
   managing telephone numbers do not align with the use cases of the
   Internet environment, and proposes a framework for Internet-based
   services relying on TNs.
