Modern Problem Statement, Use Cases, and Framework
draft-ietf-modern-problem-framework-02.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.
