In this paper, we propose a simplified way of voice communication over Wireless Local Area Network (WLAN) using Internet Protocol, without using internet connectivity at any end in enclosed system. A voice signal is converted into an electrical signal using a microphone and this analog signal will be converted into a digital signal using appropriate quantization level and sampling rate. This digital data is then transmitted over the WLAN network using internet protocol in certain defined packet size, i.e. 8 bit digital packet. At the receiver's end, packets passed through WLAN are received as is, which are combined and converted back to the transmitted analog signal from transmitter's end. These signals can be combined into sound signal through a speaker connected with receiving computer. This method of communication over internet protocol is generally called VoIP, i.e. Voice over Internet Protocol. This method can replace the current PBX telephonic network inside organizations. The demonstration of this mode of communication has been successfully done on institute WLAN with the VoIP server.
