Technical Summary

  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.

Working Group Summary

  There was some controversy when the MODERN working group was formed about
  the scope of work for the group. Discussions around these concerns resulted
  in clarifications of the architecture and requirements reflected in this
  document. In the end there was strong working group consensus on the
  contents of this document.
