CHAPTER 1

Getting To Know Your Prestige

This chapter describes the key features and applications of your Prestige.

The Prestige 2000W_V2 is a wireless telephone that operates over the Internet. It gives you
the benefits of Internet telephony, for example cheaper calls, without the physical restrictions
of a fixed Internet connection (it provides mobility).

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

The Prestige allows you to make and receive VoIP calls as long you are within range of an
IEEE 802.11b enabled wireless network.

The Prestige is easy to use and configure via the LCD display and keypad. You can even
manage your settings over the Internet using the Prestige's web configurator.

1.1 Features

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.

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.

Auto-provisioning

Auto-provisioning automatically updates your Prestige’s configurable settings via a server
hosted by your VoIP service provider.

STUN

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

Outbound Proxy

Some VoIP service providers use a SIP outbound server to handle voice calls. This allows the
Prestige to work from behind any type of NAT router and eliminates the need for STUN or a
SIP ALG (Application Layer Gateway).

Voice Coding

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

•G.711

•G.729

Voice Activity Detection/Silence Suppression

Voice Activity Detection (VAD) reduces the bandwidth that a call uses by not transmitting
when you are not speaking. This also helps increase the battery lifetime.

Comfort Noise Generation

The Prestige generates background noise to fill moments of silence when the other device in a
call stops transmitting because the other party is not speaking (as total silence could easily be
mistaken for a lost connection).

PPPoE

PPPoE (Point-to-Point Protocol over Ethernet) facilitates the interaction of a host with an
Internet modem to achieve access to high-speed data networks via a familiar "dial-up
networking" user interface.

Firmware Upgrades

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

1.2 Applications

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

1.2.1 Place a Call via “SIP Proxy Server” (SIP Call Server)

When you have a (IEEE 802.11b) wireless connection to the Internet, you can use the Prestige
to make and receive VoIP telephone calls through an Internet Telephony Service Provider’s
(ITSP) call server.

VoIPon www.voipon.co.uk [e-mail] Tel: [phone] Fax: [phone]

You don’t need to know if the recipient’s connection type is an IP, cellular or landline based
service. Your Prestige can call any landline or mobile telephone that a traditional PSTN
telephone can connect to as well the IP telephone network. Calls received from IP telephones
works exactly as you would expect from the traditional telephone service.

Figure 1 SIP Proxy Server Application

The Prestige registers with a SIP proxy server in the following circumstances:

• Your connection uses an IP Telephony Service.

• Your connection is based in a corporate VoIP environment.

1.2.2 Direct IP to IP Calling

Use the Prestige to make a call to the recipient’s IP address without using a SIP proxy server.

Figure 2 IP to IP Calling

1.2.3 Ad-Hoc (Wireless Intercom)

Ad-hoc mode does not require an AP or a wired network. Two or more wireless clients
communicate directly with each other.

• There is no intermediate SIP proxy server

• Use the phone book to directly call to the recipient’s IP address.

• The wireless mode is set to “Ad-hoc”, with the same SSID and channel
