Warning: Ensure that you connect FXS ports to analog telephone or to PBX-trunk
lines only and FXO ports to CO/PBX lines only.
Warning: Disconnect the gateway from the mains and from the Telephone Network
Voltage (TNV) before servicing.
Warning: To protect against electrical shock and fire, use a 26 AWG min wire to
connect FXO ports to the Public Switching Telephone Network (PSTN).
Warning: The FXO port is considered to be TNV-3. FXS ports are considered to be
TNV-2.
Note: Throughout this manual, unless otherwise specified, the term gateway refers
to the Mediant 1000.
Note: The terms IP-to-Tel and Tel-to-IP refer to the direction of the call relative to
the AudioCodes device: IP-to-Tel refers to calls received from the IP network
and destined to the PSTN (i.e., telephone connected directly or indirectly to
the device); Tel-to-IP refers to calls received from the PSTN and destined for
the IP network.
Note: Throughout this manual, the term 'Trunk' is used synonymously with 'Hunt'.
Trunk typically refers to digital modules, while Hunt typically refers to analog
modules.

SIP User's Manual 1. Overview
1 Overview
The AudioCodes Mediant 1000 is a best-of-breed Voice-over-IP (VoIP) SIP media
gateway, using field-proven, market-leading technology, implementing analog and digital
cutting-edge technology. The Mediant 1000 is designed to seamlessly interface between
TDM and IP networks, providing superior voice quality and optimized packet voice
streaming (voice, fax, and data traffic) over IP networks.
The Mediant 1000 is best suited for small-to-medium size (SME) enterprises, branch
offices, or for residential media gateway solutions. The Mediant 1000 is a highly scalable
and modular system that matches the density requirements for smaller environments, while
meeting service providers' demands for growth.
The Mediant 1000 is ideal for connecting an enterprise's legacy telephones, fax machines
and PBX systems to IP-based telephony networks, as well as for seamless connection of
IP-based PBX architecture to the PSTN. In addition to operating as a pure media gateway,
the Mediant 1000 open platform extends its flexibility with additional deployment options to
host partner applications, known as the Open Solutions Network (OSN) Server for
supporting third-party VoIP applications such as IP-PBX, Pre-Paid, and IP-PBX
redundancy.
The Mediant 1000 also provides conferencing services over VoIP networks. This is
supported by an optional Media Process module (MPM) that can be housed in the Mediant
1000 chassis.
The Mediant 1000 is fully interoperable with multiple vendor gateways, softswitches, SIP
servers, gatekeepers, proxy servers, IP phones, session border controllers, and firewalls.
The Mediant 1000 is designed to meet NEBS Level 3 (Bellcore) and regulatory approval
(including Safety, EMC, and Telecom for USA, EU and other countries).
Intelligently packaged in a stackable 1U chassis, the Mediant 1000 gateways are very
compact devices that can be mounted as desk-top units, on the wall, or in standard 19-inch
racks. The Mediant 1000 is provided with two integral mounting brackets for facilitating rack
installation.
Mediant 1000 units are equipped with two 10/100 Base-TX Ethernet ports for connection to
the IP network. The second Ethernet port is used for 1+1 Ethernet redundancy.
The Mediant 1000 supports mixed digital and analog interface configurations:
The Mediant 1000 digital interface supports multiples of 1, 2, or 4 E1/T1/J1 spans
used for connecting the PSTN or PBX to the IP network. The digital modules provide
RJ-48 ports. The digital module can be configured as regular E1/T1/J1 interfaces, and
with up to 1 or 2 paired spans acting as Lifeline telephone interfaces for switching to
the PSTN in case of power failure or network problems.
The Mediant 1000 analog interface supports up to 24 analog ports (four ports per
module) in various Foreign Exchange Office (FXO) or Foreign Exchange Station
(FXS) configurations, supporting up to 24 simultaneous VoIP calls. Each analog
module comprises four analog RJ-11 ports. The FXO module can be used to connect
analog lines of an enterprise's PBX or of the PSTN to the IP network. The FXS module
can be used to connect legacy telephones, fax machines, and modems to the IP
network. Optionally, the FXS module can be connected to the external trunk lines of a
PBX. When deployed with a combination of FXO and FXS modules, the Mediant 1000
can be used as a PBX for Small Office Home Office (SOHO) users, and businesses
not equipped with a PBX.

Mediant 1000
The Mediant 1000 has enhanced hardware and software capabilities to ease its installation
and to help maintain voice quality. If the measured voice quality falls beneath a pre-
configured value, or the path to the destination is disconnected, the Mediant 1000 can
assure voice connectivity by falling back to the PSTN. In the event of network problems or
power failures, calls can be routed back to the PSTN without requiring routing modifications
in the PBX. Further reliability is provided by dual Ethernet ports and optional dual AC
power supply.
The Mediant 1000 supports various ISDN PRI protocols such as EuroISDN, North
American NI2, Lucent™ 4/5ESS, Nortel™ DMS100 and others. In addition, it supports
different variants of CAS protocols for E1 and T1 spans, including MFC R2, E&M
immediate start, E&M delay dial / start, loop start and ground start.
The Mediant 1000 provides a user-friendly embedded HTTP-based Web server for remote
configuration and management using a standard Web browser (such as Microsoft™
Internet Explorer™ or Netscape™ Navigator™), from anywhere in the world with IP
connectivity to the device.
1.1 SIP Overview
Session Initialization Protocol (SIP) is an application-layer control (signaling) protocol used
on the gateway for creating, modifying, and terminating sessions with one or more
participants. These sessions can include Internet telephone calls, media announcements,
and conferences.
SIP invitations are used to create sessions and carry session descriptions that enable
participants to agree on a set of compatible media types. SIP uses elements called Proxy
servers to help route requests to the user's current location, authenticate and authorize
users for services, implement provider call-routing policies and provide features to users.
SIP also provides a registration function that enables users to upload their current locations
for use by Proxy servers. SIP implemented in the gateway, complies with the Internet
Engineering Task Force (IETF) RFC 3261 (refer to http://www.ietf.org.)
