Abstract
This memo describes a simple method of encoding Global Switched
Telephone Network (GSTN) addresses (commonly called "telephone
numbers") in the local-part of Internet email addresses, along with
an extension mechanism to allow encoding of additional standard
attributes needed for email gateways to GSTN-based services.
1. Introduction
As with all Internet mail addresses, the left-hand-side (local-part)
of an address generated according to this specification, is not to be
interpreted except by an MTA that handles messages for the domain
given in the right-hand-side.
Since the very first e-mail to GSTN services gateway appeared, a
number of different methods to specify a GSTN address as an e-mail
address have been used by implementors. Several objectives for this
methods have been identified, like to enable an e-mail user to access
GSTN services from his/her e-mail interface, to allow some kind of
"GSTN over e-mail service" transport (possibly reducing the costs of
GSTN long distance transmissions) while using the existing e-mail
infrastructure.
