Cheap VoIP services enable you to make phone calls at a fraction of the cost of a traditional phone service. They are provided by companies that use VoIP or voice over Internet Protocol technology that allows voice signals to be transmitted over the Internet.
One reason the VoIP services are cheap is that the service providers don t have to invest on infrastructure. They use the existing Internet infrastructure to route voice traffic. This reduces costs, because the VoIP services provider only has to pay termination fees to telecom majors when the call passes beyond the net to traditional phone lines.
If the call is made from an Internet-enabled phone to another Internet-enabled phone then the phone provider incurs no cost. This provides big savings that are passed on to the customer.
