VOIP Equipment

What telephone equipment do I need?

You will require some type of Voip IP Telephony device. This may come in the form of:

1. Voip IP or SIP Telephone. This is like a normal phone except that it communicates using an IP connection. These phones plug straight into your router, LAN or LAN hub.  You do not need to have your PC on to use this.

2. Softphone. This is an application that runs on your PC and uses your PC's soundcard and microphone for telephone conversations.

3. Analogue Telephone Adaptor (ATA). This device converts analogue traffic from your analogue (normal BT type phone) into IP traffic. This device is similar to a VoIP Gateway device except, depending upon the model chosen, is designed to connect single or multiple analogue phones.

4. VoIP Gateway. This device converts analogue traffic from your analogue phones into VoIP traffic. They are usually referred to as FXS (Foreign Exchange Station) devices.
