The use of Wi-Fi enabled cell phones to access internet away from the PC is increasing day-by-day. The use of Wi-Fi enabled phones as IP phones, and their communication within a local wireless LAN is discussed in this paper. This proposed model is a form of telecommunication that allows data and voice transmissions to be sent within a specific range of interconnected networks. The models, which are Wi-Fi enabled, can be used to communicate with each other through the Wi-Fi communication channel. Each mobile device connects to a device which hosts the Server which is a part of the network and identifies itself in the routing table. Our proposal allows free calls within the network with high quality voice transmission. This model will be a prototype of itinerant devices communicating through in the Wi-Fi bandwidth and will greatly reduce the communication cost in large organizations.
