The main principle of VoIP is voice transferring via the Internet. Analog signals are converted into digital packets and sent through Internet protocol. Before reaching the destination they are reconverted into analog signals so that the listener will be able to comprehend. VoIP provider carries out the majority of work i.e. offers wholesale VoIP termination whereas resellers don`t have to worry about the transmission process and technical nuances. So it`s more logical and easier for a business to become VoIP reseller and get a profit out of these popular services.
