Traditional public switch telephony network or PSTN has enabled us to make quality calls across the globe for more than a decade now. The high call tariff has always been seen as a huge let down for a service which is absolute essential for both business and residential townships. The ever increasing telephony bills have been a cause of worry for business houses who thrive on telephones for communicating with their clients, dealers, and suppliers among others. This was all but a thing of past. With the advent of cheapest solution VoIP, entrepreneurial houses no longer have to think twice before calling their overseas clients. The ability to make calls at less than half the call tariff of traditional mode of communication has placed VoIP solution in stiff competition against PSTN service.
