The seeds of VoIP were sown about 10 years ago, when hobbyists developed software that could convert voice into data and back again. The slow speed of modems in the mid-Nineties meant that anyone trying out VoIP would be engaged in a fruitless exchange, with long silences punctuated by both people talking at once. But it remained a toy with potential, and by 1997 VoIP was carrying 7.5 million minutes of international voice traffic.

Since then the figure has increased enormously, thanks to broadband. Anyone with a speedy internet connection, a computer with a soundcard and some VoIP software can talk to other users of that same piece of software - for example, Skype - for free. But most of us need our telephone service to be able to call numbers on the traditional telephone network, so gateways have been built to enable VoIP users to dial the real world, for a small charge. So it's cheap - but is it cheerful? One of the continuing problems is the need, with some VoIP providers, for you to sport a headset with a built-in microphone in order to suppress feedback when engaged in conversation. Other VoIP companies are ahead of the game: telephone-like handsets can be purchased which connect to your computer in the same way as a headset, while others offer adaptors which plug into your broadband connection, and to which you simply connect a standard telephone. This eliminates the need for your computer to be switched on, allowing your VoIP line to behave just like a normal landline.

But does it? Fizz, dropouts and crackle are still commonplace when networks are congested. Some providers don't give you the opportunity to receive calls via VoIP, only make them, and many are unable to provide access to emergency services. Then there are hidden costs: many rates are advertised as being free of charge, but as a broadband customer you're already paying out as much as £30 a month to have the facility to use VoIP in the first place.
