Voice Over IP Services

If you've never heard of VoIP, get ready to change the way you think about how you make phone calls. VoIP, or Voice over Internet Protocol, is a method for talking over the Internet rather than traditional phone lines.
How is this useful? You've already paid for your broadband connection so effectively you can avoid expensive phone company charges. Telephone calls between VoIP systems are completely free and calls to ordinary telephone numbers from a VoIP phone are charged at a fraction of the cost.
With VoIP and a suitable mobile phone, you can make a call from anywhere you have broadband connectivity, say from a free wireless hotspot in a cafe in Europe! and your call charges are based on you being in the UK!
By default you will be allocated a normal UK telephone number for incoming calls but multiple incoming numbers are also configurable.
