Version 5.6 15 November 2008
SIP User's Manual 1. Overview
1 Overview
This manual provides you with the information for installing, configuring, and operating the
Mediant 2000 SIP gateway (referred to throughout this manual as device).
The device is a SIP-based Voice-over-IP (VoIP) media gateway. the device enables voice,
fax, and data traffic to be sent over the same IP network.
The device provides excellent voice quality and optimized packet voice streaming over IP
networks. The device uses the award-winning, field-proven VoIPerfect™ voice compression
technology, typically implemented in AudioCodes products.
The device incorporates 1, 2, 4, 8 or 16 E1, T1, or J1 spans for direct connection to the
Public Switched Telephone Network (PSTN) / Private Branch Exchange (PBX) through
digital telephony trunks. The device also provides SIP trunking capabilities for Enterprises
operating with multiple Internet Telephony Service Providers (ITSP) for VoIP services. The
device includes two 10/100Base-TX Ethernet ports, providing redundancy connection to the
network.
The device supports up to 480 simultaneous VoIP or Fax over IP (FoIP) calls, supporting
various Integrated Services Digital Network (ISDN) Primary Rate Interface (PRI) protocols
such as EuroISDN, North American NI2, Lucent™ 4/5ESS, Nortel™DMS100 and others. In
addition, it supports different variants of Channel Associated Signaling (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 device, best suited for large and medium-sized VoIP applications is a compact device,
comprising a 19-inch, 1U chassis with optional dual AC or single DC power supplies. The
deployment architecture can include several devices in branch or departmental offices,
connected to local PBXs. Call routing is performed by the devices using internal routing or
SIP Proxy(s).
The device enables users to make cost-effective, long distance or international
telephone/fax calls between distributed company offices, using their existing
telephones/fax. These calls can be routed over the existing network using state-of-the-art
compression techniques, ensuring that voice traffic uses minimum bandwidth.
The device can also route calls over the network using SIP signaling protocol, enabling the
deployment of Voice over Packet solutions in environments where access is enabled to
PSTN subscribers by using a trunking device. This provides the ability to transmit voice and
telephony signals between a packet network and a TDM network.
Notes:
•The device is offered as a 1-module (up to 240 channels or 8 trunk
spans) or 2-module (for 480 channels or 16 trunk spans only) platform.
The latter configuration supports two TrunkPack modules, each having its
own IP address. Configuration instructions in this document relate to the
device as a 1-module platform and must be repeated for the second
module as well.
•For channel capacity, refer to the device's specifications in ''Selected
Technical Specifications'' on page 409.

Mediant 2000
The figure below illustrates a typical device applications VoIP network:
Figure 1-1: Mediant 2000 Typical Application
1.1 SIP Overview
Session Initiation 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).

SIP User's Manual 2. Configuration Concepts
2 Configuration Concepts
You can configure the device's parameters (including upgrading the software, and
uploading configuration and auxiliary files), using the following tools:
An HTTP-based Embedded Web Server (Web interface), using any standard Web
browser (described in ''Web-based Management'' on page 19).
A configuration file referred to as the ini file (refer to ''ini File Configuration'' on page
255).
Simple Network Management Protocol (SNMP) browser software (refer to the Product
Reference Manual).
AudioCodes’ Element Management System (refer to AudioCodes’ EMS User’s Manual
or EMS Product Description).
Note: To initialize the device by assigning it an IP address, a firmware file (cmp),
and a configuration file (ini file), you can use AudioCodes' BootP/TFTP utility,
which accesses the device using its MAC address (refer to the Product
Reference Manual).

Reader’s Notes
Version 5.6 19 November 2008
SIP User's Manual 3. Web-Based Management
3 Web-Based Management
The device's Embedded Web Server (Web interface) provides FCAPS (fault management,
configuration, accounting, performance, and security) functionality. The Web interface
allows you to remotely configure your device for quick-and-easy deployment, including
uploading of configuration (software upgrade) and auxiliary files, and resetting the device.
The Web interface provides real-time, online monitoring of the device, including display of
alarms and their severity. In addition, it displays performance statistics of voice calls and
related traffic parameters.
The Web interface provides a user-friendly, graphical user interface (GUI), which can be
accessed using any standard Web browser (e.g., Microsoft™ Internet Explorer). Access to
the Web interface is controlled by various security mechanisms such as login user name
and password, read / write privileges, and limiting access to specific IP addresses.
Notes:
•The Web interface allows you to configure most of the device's
parameters. Those parameters that are not available in the Web interface
can be configured using the ini file.
•Certain Web interface pages are feature-key dependant, and therefore,
only appear if your device's feature key supports the features relating to
these pages (refer to “Upgrading the Software Upgrade Key” on page
233).
•Throughout this section, parameters enclosed in square brackets [...]
depict the ini file parameters for configuring the device using the ini file.
3.1 Computer Requirements
To use the device's Web interface, the following is required:
A connection to the Internet network (World Wide Web).
A network connection to the device's Web interface.
One of the following Web browsers:
•Microsoft™ Internet Explorer™ (version 6.0 or later).
•Netscape™ Navigator™ (version 7.2 or later).
•Mozilla Firefox®(version 1.5.0.10 or later).
Recommended screen resolution of 1024 x 768 pixels, or 1280 x 1024 pixels.
Note: Your Web browser must be JavaScript-enabled in order to access the Web
interface.
SIP User's Manual 20 Document #: LTRT-68808
Mediant 2000
3.2 Accessing the Web Interface
The Web interface can be opened using any standard Web browser (refer to ''Computer
Requirements'' on page 19). When initially accessing the Web interface, use the default
user name ('Admin') and password ('Admin'). For changing the login user name and
password, refer to ''Configuring the Web User Accounts'' on page 99).
¾To access the Web interface, take these 4 steps:
1. Open a standard Web browser application.
2. In the Web browser's Uniform Resource Locator (URL) field, specify the device's IP
address (e.g., http://10.1.10.10); the Web interface's 'Enter Network Password' dialog
box appears, as shown in the figure below:
Figure 3-1: Enter Network Password Screen
3. In the 'User Name' and 'Password' fields, enter the case-sensitive, user name and
password.
4. Click the OK button; the Web interface is accessed, displaying the 'Home' page (for a
detailed description of the 'Home' page, refer to ''Using the Home Page'' on page 46).
Note: If access to the device's Web interface is denied ("Unauthorized") due to
Microsoft Internet Explorer security settings, perform the following
troubleshooting procedures:
1. Delete all cookies in the Temporary Internet Files folder. If this does not
resolve the problem, the security settings may need to be altered
(continue with Step 2).
2. In Internet Explorer, navigate to Tools menu > Internet Options >
Security tab > Custom Level, and then scroll down to the Logon options
and select Prompt for username and password. Select the Advanced
tab, and then scroll down until the HTTP 1.1 Settings are displayed and
verify that Use HTTP 1.1 is selected.
3. Quit and start the Web browser again.
