Abstract

   There are numerous applications where there is a need for interaction
   between the GSTN addressing and Internet addressing.  This memo
   defines a full syntax for one specific case, where there is a need to
   represent GSTN addresses within Internet e-mail addresses. This full
   syntax is a superset of a minimal syntax which has been defined in
   [1].

1. Introduction

   The possible elements composing a "Global Switched Telephone Network
   (GSTN) address in e-mail" (also known as the Public Switched
   Telephone Network - PSTN) can vary from a minimum number up to a
   really large and complex collection. As noted the minimal format and
   general address syntax have been defined in [1], along with the
   mechanism needed to define additional address elements. This memo
   uses this extension mechanism to complete the syntax for representing
   GSTN addresses within e-mail addresses and contains the IANA
   registrations for all newly defined elements.

   In particular, the following additional address elements shall be
   defined:

   -  the detailed definition of GSTN number formats, in order to cover
      various alternative standard GSTN numbering schemes, (i.e. gstn-
      phone, sub-addr-spec and post-dial)
