Title : Interworking between SIP and QSIG

This document specifies interworking between the Session Initiation
Protocol (SIP) and QSIG within corporate telecommunication networks
(also known as enterprise networks). SIP is an Internet application-
layer control (signalling) protocol for creating, modifying, and
terminating sessions with one or more participants. These sessions
include, in particular, telephone calls. QSIG is a signalling
protocol for creating, modifying and terminating circuit-switched
calls, in particular telephone calls, within Private Integrated
Services Networks (PISNs). QSIG is specified in a number of ECMA
Standards and published also as ISO/IEC standards.
As the support of telephony within corporate networks evolves from
circuit-switched technology to Internet technology, the two
technologies will co-exist in many networks for a period, perhaps
several years. Therefore there is a need to be able to establish,
modify and terminate sessions involving a participant in the SIP
network and a participant in the QSIG network. Such calls are
supported by gateways that perform interworking between SIP and QSIG.
This document is a product of the authors' activities in ECMA
(www.ecma.ch) on interoperability of QSIG with IP networks.

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.
