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-00.txt
	Pages           : 11
	Date            : 2008-02-18

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.
