A new opportunity to reduce communication costs has arisen with the ability to convey international telephone calls across the internet using voice over internet protocol (VoIP).
The adoption of VoIP is being driven by the efficiency savings of having to maintain only one communications infrastructure. A simple analogy can be drawn from the use of road transport. A road is used for a variety of vehicles – cars, lorries and buses. A bus user requires a greater level of punctuality than either a car or a lorry user. There are two ways of increasing the punctuality of buses: either create a separate road for buses or give priority to buses on an existing road by means of a bus lane.
