Application for voice transfer through Internet protocol

This text shows program solution for transferring voice data through Internet protocol. In order to transfer data between two or more terminals, specific steps are needed in HW and SW to get media information and adjust them for sending through computer network. Applications in the Java environment, analyzing the properties of the human voice, such as the frequency spectrum and frequency of recurrence sequences, and presents procedures digitizing speech. Described methods of creating the flow of data and displayed during the creation of a session in the application and the process of creating sockets for data and control channels. For satisfying quality, network must be able to transfer at certain speed and with minimum delay. Program code has to be optimized so that any terminal delays in performing programmed functions are down to their minimum level. The results of testing applications on the network using Ethereal software package are shown measurements.
