As with the internet you subscribe to a provider. You normally need to install their software onto your PC but with some models you can just connect them to the PC via a USB cable and start dialling.

What are the advantages?
Mainly price. If you call someone who’s on the same provider as you are (e.g. Skype™) your calls are free – from anywhere in the world. Receiving or making calls from/to other networks will incur a charge but these are very small.

Are there any disadvantages?
You normally need to have the PC switched on, so if there’s a problem with your PC, or with your broadband connection, you may not be able to use it. It’s also not recommended to use one for an emergency call as calls are not traceable. It’s a good idea to have a mobile or normal landline as back up.

Can I use it anywhere?
Yes. As it’s connected to your PC, simply take it with you anywhere in the world and it will still work.

What do the handsets look like?
Basic models look and behave the same way as conventional handsets, with LCD screen, name and number directories. There are hands-free and cordless models also available.

What’s the quality of the call like?
You and the person at the other end of the line shouldn’t hear any difference. The VoIP phone even rings like a normal phone.
