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

	Title		: Private SIP Extension for Mobile Charging Information
	Author(s)	: E. Henrikson
	Filename	: draft-henrikson-sip-charging-information-02.txt
	Pages		: 9
	Date		: 22-May-02
This memo describes a private extension to SIP in the form of  
P-Charging-Function-Addresses and P-Charging-Vector headers. The 
former header is used to pass the addresses of entities that 
provide a charging function. The latter header is used to pass 
charging correlation information. The affected UAs and proxies 
associated with a dialog or standalone transaction need to know the 
identities or addresses of the appropriate charging entities. They 
also need to pass correlation information so that the records 
generated and sent to the charging entities may be properly 
associated for a coordinated billing effort.

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.
