Prestige 2002 Series User’s Guide

CHAPTER 1

Introducing the Prestige

This chapter introduces the main features and applications of the Prestige.

1.1 Prestige 2002 VoIP Analog Telephone Adaptor Overview

The Prestige 2002 is a SIP-based VoIP analog telephone adaptor (ATA). Sending voice
signals over the Internet is called Voice over IP or VoIP. Session Initiated Protocol (SIP) is an
internationally recognized standard for implementing VoIP.

The Prestige allows you to use a traditional analog telephone to make and receive Voice over
IP calls. You can call any landline or mobile telephone as well as IP telephones. You don’t
need to know if the recipient’s connection type is an IP, cellular or landline based service.
Calls received from IP telephones work exactly as you would expect from the traditional
telephone service.

The Prestige’s two Ethernet ports allow you to connect the Prestige to your LAN and connect
your computer to the Prestige. This way your computer can still access the LAN without
adding an extra Ethernet switch.

The Prestige's web configurator allows easy management and configuration.

1.2 Prestige 2002L VoIP Analog Telephone Adaptor with Lifeline

The Prestige 2002L has all of the features of the Prestige 2002 and adds the PSTN (Public
Switched Telephone Network) lifeline feature. PSTN lifeline lets you have VoIP phone
service and PSTN phone service at the same time.

1.3 Features

Your Prestige is packed with a number of features that make it flexible and easy to use.

10/100Mbps Auto-negotiating Fast Ethernet Interfaces

The auto-negotiation feature allows the Prestige to detect the speed of incoming transmissions
and adjust appropriately without manual intervention. It allows data transfer of either 10 Mbps
or 100 Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.

Auto-crossover 10/100 Mbps Ethernet Interfaces

The Ethernet interfaces automatically adjust to either a crossover or straight-through Ethernet
cable.

Chapter 1 Introducing the Prestige 17

Prestige 2002 Series User’s Guide

PSTN Lifeline

The Prestige 2002L has a LINE port for connecting a PSTN line. You can receive incoming
PSTN phone calls even while someone else connected to the Prestige is making VoIP phone
calls. You can dial a (prefix) number to make an outgoing PSTN call. You can still make
PSTN phone calls if the Prestige 2002L loses power.

REN

A Ringer Equivalence Number is used to determine the number of devices that may be
connected to the telephone line. The Prestige can support three devices per telephone port.

Dynamic Jitter Buffer

The Prestige has a built-in adaptive, buffer that helps to smooth out the variations in delay
(jitter) for voice traffic. This helps ensure good voice quality for your conversations.

Standards Compliance

The Prestige complies with the following standards.

• SIP version 2 (RFC 3261)

• SDP (RFC 2327)

• RTP (RFC 1889)

• RTCP (RFC 1890)

• SIP NAT Traversal (STUN) (RFC 3489)

Multiple SIP Accounts

The Prestige allows you to simultaneously use multiple voice (SIP) accounts and assign them
to one or both telephone ports.

STUN

Simple Traversal of User Datagram Protocol (UDP) through Network Address Translators
(STUN) allows SIP to pass through NAT routers.

Multiple Voice Channels

The Prestige can simultaneously handle multiple voice channels (telephone calls).
Additionally you can answer an incoming phone call on a VoIP account, even while someone
else is using the account for a phone call.

Voice Coding

The Prestige can use the following voice codecs (coder/decoders).

•G.711

•G.729

18 Chapter 1 Introducing the Prestige

Prestige 2002 Series User’s Guide

Voice Activity Detection/Silence Suppression

Voice Activity Detection (VAD) reduces the bandwidth that a call uses by not transmitting
“silent packets” when you are not speaking.

Comfort Noise Generation

When the Prestige uses VAD, it generates and sends comfort (background) noise when you are
not speaking.

Echo Cancellation

The Prestige supports G.168, an ITU-T standard for eliminating the echo caused by the sound
of your voice reverberating in the telephone receiver while you talk.

QoS (Quality of Service)

Quality of Service (QoS) mechanisms help to provide better service on a per-flow basis. The
Prestige supports Type of Service (ToS) and Differentiated Services (DiffServ). This allows
the Prestige to tag voice frames so they can be prioritized over the network.

Fax Tone Detection and Pass-through

The Prestige automatically detects fax messages and sends them over PCM G.711.

Auto-provisioning

Auto-provisioning automatically updates your Prestige’s configurable settings via a TFTP
server.

Firmware Upgrades

Use the web configurator to upload updated firmware to your Prestige.

Ease of Installation

Your Prestige is designed for quick, intuitive and easy installation. Physically, its compact size
and lightness make it easy to position anywhere in your busy office.

1.4 Applications

Here are some examples of how you can use your Prestige.

1.4.1 Make Calls via Internet Telephony Service Provider

In a home or small office environment, you can use the Prestige to make and receive VoIP
telephone calls through an Internet Telephony Service Provider (ITSP).

Chapter 1 Introducing the Prestige 19

Prestige 2002 Series User’s Guide

The following figure shows a basic example of how you would make a VoIP call through an
ITSP. You use your analog phone (A in the figure) and the Prestige (B) changes the call into
VoIP. The Prestige then sends your call through your modem or router (C) to the Internet and
the ITSP’s SIP server. The VoIP call server forwards calls to PSTN phones (F) through a
trunking gateway (E) to the PSTN network. The VoIP call server forwards calls to IP phones
(G) through the Internet.

Figure 1 Internet Telephony Service Provider Application

1.4.2 Make Calls via IP-PBX

If your company has an IP-PBX (Internet Protocol Private Branch Exchange), you can use the
Prestige to make and receive VoIP telephone calls through it.

In this example, you use your analog phone (A in the figure) and the Prestige (B) changes the
call into VoIP and sends it to the IP-PBX. The IP-PBX forwards calls to PSTN phones (C) to
the PSTN network. The IP-PBX forwards calls to IP phones (D) through an IP network (this
could include the Internet).

Introducing the Web

This chapter describes how to access the Prestige web configurator and provides an overview
of its screens.

2.1 Web Configurator Overview

The embedded web configurator allows you to manage the Prestige from anywhere through a
browser such as Microsoft Internet Explorer or Netscape Navigator. Use Internet Explorer 6.0
and later or Netscape Navigator 7.0 and later versions with JavaScript enabled.

It is recommended that you set your screen resolution to 1024 by 768 pixels.

2.2 Accessing the Prestige Web Configurator

1 Make sure your Prestige hardware is properly connected and prepare your computer/

computer network to connect to the Prestige (refer to the Quick Start Guide).

2 Launch your web browser.

3 Enter the Prestige’s management IP address (default 192.168.5.1) or IP address. The

Prestige 2002 has a management IP address feature since by default the Prestige is set to
receive a dynamically assigned IP address and thus has no default IP address. Whether
you use the Prestige’s management IP address or its IP address (after it receives one),
make sure that your computer’s IP address is in the same subnet.

password appears automatically - if this is the case, click Login.

if this happens to you.

2.3 Resetting the Prestige

If you forget your password or cannot access the web configurator, you will need to reload the
factory-default configuration file or use the RESET button the back of the Prestige. Uploading
this configuration file replaces the current configuration file with the factory-default
configuration file. This means that you will lose all configurations that you had previously.
The password will also be reset to “1234”.

2.3.1 Procedure To Use The Reset Button

Make sure the PWR/VoIP LED is on (not blinking) before you begin this procedure.

1 Press the RESET button for five to ten seconds (release it when the PWR/VoIP LED

begins to blink). When the PWR/VoIP LED starts blinking, the defaults have been
restored and the Prestige restarts. Otherwise, go to step 2.

2 Disconnect and reconnect the Prestige’s power.

3 Wait for the PWR LED to stop blinking and stay on steady.

4 Press the RESET button for five to ten seconds (release it when the PWR/VoIP LED

begins to blink). When the PWR/VoIP LED starts blinking, the defaults have been
restored and the Prestige restarts. Otherwise, go to step 2.

Type how many minutes a management session can be left idle before the session
times out. The default is 5 minutes. After it times out you have to log in with your
password again. Very long idle timeouts may have security risks. A value of "0"
means a management session never times out, no matter how long it has been left
idle (not recommended).

3.4 Configuring Password

To change your Prestige’s password (recommended), click SYSTEM in the navigation panel,
