 A Framework and Information Model for Telephone-Related Queries (TeRQ)
                         draft-peterson-terq-04

Abstract

   As telephone services migrate to the Internet, Internet applications
   require access to diverse information about telephone numbers.  ENUM,
   for example, applied the DNS to the problem of finding URIs for
   telephone services on the Internet.  The intrinsic limitations in the
   query/response semantics of the DNS, however, have often been
   strained by the requirements for accessing information about
   telephone numbers.  This document therefore proposes a protocol-
   independent framework and information model for querying and
   responding to requests concerning telephone numbers and call routing
   that allows a richer expression of both questions and answers.
