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.

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.
