I-D ACTION:draft-jennings-sipping-pay-03.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.

	Title		: Payment for Services in Session Initiation Protocol (SIP)
	Author(s)	: C. Jennings, et al.
	Filename	: draft-jennings-sipping-pay-03.txt
	Pages		: 33

Service usage might require some form of compensation and this is
   also true for many communication systems where an entity receiving a
   call should be able to charge the caller.  This is necessary for
   allowing fair communication between two communicating parties and is
   a major strategy for reducing the viability of SPAM.  This draft
   proposes an approach for doing this in SIP using the Security
   Assertion Markup Language (SAML).  It relies on a third party to act
   as a payment provider and is designed for low value transactions.  It
   does not aim to provide the same capability as other authentication,
   authorization and accounting systems.

   This draft is in a fairly early state and has many details that are
   missing.  Earlier versions of this document did not use SAML.  This
   version offers a sketch of what the SAML based solution would look
   like but still lacks many details that would be needed for an actual
   implementation.

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
