Title : Private Extensions to the Session Initiation Protocol (SIP) for Service Interaction Indicator
Author(s) : Y. Shen
Filename : draft-shen-interaction-ind-02.txt

In SIP-based networks, a SIP session MAY involve several application
servers on the originating and terminating side. In a certain case,
an application server needs to set some indications in SIP message to
indicate service information (what are invoked, what can be allowed
and what should blocked). This kind of information will be also
required for composition of SIP applications. There is a need to
provide indicators for service interaction between SIP application
servers or other SIP endpoints.
This document describes a mechanism of service interaction indicator
for the Session Initiation Protocol (SIP) that enhances service
interaction between SIP application servers in a trusted network.

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
