SIP  is an excellent vehicle for the converged network services of
the future; of that there is no doubt. However, even in the near
term, SIP is an equally powerful solution to bridge the PSTN and VoIP
networks by its application to the IN (Intelligent Network) services
This Internet Draft details our experiences of applying SIP to the
said domain. We use a SIP call controller to execute IN services by
mapping IN call model states to those of the SIP protocol state
machine .  uses the notion of call model integration , an
example of which is to use the IN call model as a canonical call
model to map the protocol states of IP (Internet Protocol) based call
controllers (SIP, H.323,...) to those of the IN call model.

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.
