A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : E.164 Ownership Problem Statement
Author(s) : D. Schwartz, et al.
Filename : draft-schwartz-sip-e164-ownership-01.txt
Pages : 15
Date : 2008-02-25
When a call travels end-to-end relayed from the PSTN to SIP then
problems occur with E.164 number ownership. Additionally, there are
security challenges when the PSTN-VoIP gateway has to authenticate
and authorize the calling party. Without addressing these two
aspects the overall security story is weak or non-existent. This
document aims to investigate these two aspect; it does, however, not
investigate current E.164 number handling with RFC 4474 ("SIP
Identity"). Such an analysis is provided by other documents already.

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.
