This is the server element of Ventrilo - in this case, a standalone, commandline application, configured via an .ini file, which runs as a service on a host PC, allowing other participants to connect to it and engage in voice chat with one other. The free Ventrilo Server application is somewhat limited in comparison with the fully-fledged, hosted solutions available (for a monthly fee), but it works well for smaller groups of gamers on a LAN, home users or people wishing to set up a temporary Ventrilo server to chat with each other. From the Ventrilo site: Ventrilo 3.0.0 is the next evolutionary step of Voice over IP (VoIP) group communications software. Ventrilo is also the industry standard by which all others measure themselves as they attempt to imitate its features. By offering surround sound positioning and special sound effects on a per user, per channel, per server or global configuration level the program provides each user the option to fully customize exactly how they wish to hear sounds from other users or events. Ventrilo is best known for its superior sound quality and minimal use of CPU resources so as not to interfere with day to day operations of the computer or during online game competitions. It is also preferred for the simple user interface that any first time computer user can very quickly learn because the most commonly used features are immediately visible and can be activated with a single click of the mouse.
