Answer

Using VOIP hardware frees up your PC and gives you better quality calls. This guide introduces the most common types of hardware, and should help you decide a suitable unit for you. The most important part of choosing hardware is to make sure it's SIP compliant, SIP is the most widely used VOIP protocol and the only one we use at freespeech.

NOTE: We do not sell VoIP hardware at freespeech, SIP compatible VoIP hardware is widely available from retail computer stores.

The most common types of hardware are

Using a regular telephone

The easiest way to use your freespeech account is with a regular analogue telephone, just like the the one your used to using at home. You will make and receive calls just like you do on a normal phone and will not need to keep your computer on. To connect a regular telephone you need what's known as an Analogue Adaptor (also refererred to as AT, ATA or TA).

Analogue Adaptors

This is an example of a basic analogue adaptor

Analogue adaptors come in many shapes and sizes but what they all have in common is they provide an analogue telephone socket (just like the traditional phone socket you have on your wall) and a (LAN) network connection socket for connecting to your router. The analogue phone socket is often referred to as an FXS (Foreign Exchange Station) port.


You connect the analogue adaptor to your computer network (LAN) via the network connection socket. Your regular phone connects to the analogue telephone socket.

This is an example of the most typical connection. When your adaptor is configured and you connect your phone, it works just like a regular phone.

Configuring an Adaptor

Most telephone adaptors use a web page for configuration (using internet explorer), many also support a voice prompt menu which you can reach by picking up the attached phone and dialing a specific code.

Additional features you can expect on adaptors

Combined VOIP Gateway/router/adaptor

This device combines the funtion of a router and adaptor into a neat package reducing the complexity of your setup. A VOIP gateway will also improve the quality of your calls by prioritising voice over data.

This is an example of the most typical connection. When your VOIP gateway is configured you can make/receive calls just like a regular phone.

Using a VOIP telephone

A VOIP phone (also known as an IP phone) is a next generation telephone which natively supports VOIP, it's like an adaptor and phone combined. VOIP phones typically give better quality than adaptors and have can have a broader set of features supported. A VOIP phone works in a similar way to a regular phone for a users perspective.

This is an example of a basic IP phone.

All IP phones are directly connected to the network with a (LAN) network cable.

This is an example of the most typical connection. When your IP phone is configured you can make/receive calls just like a regular phone.

Configuring an IP phone

Most IP phones use a web page for configuration (using internet explorer), many also have a menu system configuration you can use with the phones display.

Additional features you can expect on IP phones
