A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : Integration of Resource Management and Call Signaling
for IP Telephony
Author(s) : K. Ramakrishnan, B. Marshall, E. Miller et.al
Filename : draft-dcsgroup-sip-resource-00.txt
Pages : 11
Date : 27-Oct-99
This document describes a two-stage call-setup mechanism, with the
resource management protocol interleaved between the two stages. The
objective of such a mechanism is to enable deployment of robust IP
Telephony services. The first phase ensures that resources are made
available before the phone rings and the participants of the call
are 'invited' to participate. The second phase involves the alerting
of the user after the network resources are reserved. This draft
presents the call signaling requirements that lead to this design,
and the specific SIP extension of an INVITE that does not ring the
far-end phone.

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
Internet-Draft.
