Title : New Parameters for the 'tel' URI to Support Number Portability
Author(s) : J. Yu
Filename : draft-ietf-iptel-tel-np-01.txt
Pages : 13
Date : 2004-4-6
This document defines several new parameters in the "tel" Uniform
Resource Identifier (URI) to support number portability (NP) for
geographical telephone numbers and freephone numbers. The "rn"
parameter carries the routing number for a ported geographical
telephone number. The presence of the "npdi" parameter indicates
that NP database dip has been performed on a geographical telephone
number. The "cic" parameter identifies the freephone service
provider for a freephone number. The "rn-context" and "cic-context"
parameters describe the "rn" and "cic" parameters respectively when
the "rn" and "cic" parameters contain information in the "local"
format.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
