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

	Title		: Payment for Services in Session Initiation
                          Protocol (SIP)

Communication systems require that a person receiving a call be able
   able to charge the caller when they are from different administrative
   domains.  This is necessary for making fair exchanges of service
   between two different communicating parties and is a major strategy
   for reducing the viability of SPAM.  This draft proposes an approach
   for doing this in SIP.  The approach relies on a third party to act
   as a payment service provider and is optimized for very simple, low
   value transactions.  It does not provide the full range of services
   that are desirable in typical online trading systems.

   This draft is being discussed on the sipping@ietf.org mailing list.
   There is currently work to substantially change this draft to use
   SAML.

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
