As Telecommunication has become a basic requirement of the today’s society there had been a vast increase of competition between the telecommunication service providers. Every service provider tries to cater the customers the best services for the lowest charges. Customers have the expectation of receiving the most recent technologies for the cheapest cost. Triple play (voice, data, content) is becoming everyone’s requirement today in communication. Voice over IP (VoIP) comes handy in considering Triple play. The design presents in the paper is an approach developed for a company that holds an Internet Service Provider (ISP) license from the Telecommunications Regulatory Commission of Sri Lanka (TRCSL) for island-wide coverage. The said company is a subsidiary of the leading Telecommunication provider of the nation. The problem faced here by the subsidiary is finding the capital cost to provide this highly exclusive IN (Intelligent Network) services to the customers in their initiation phase to cope with the existing competition. As an optimum solution, came up with the idea of accessing existing legacy PSTN core network of the leading telecommunication service provider which enhances most of the highly exclusive services. The system presented in the paper is a small model of an existing network that allows online billing facility for data calls as an IN facility.
