VentriloFlagship Industries - (Freeware)
Ventrilo 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.
Ventrilo is comprised of two primary Components: The Client that every end user will need to download, and the Server. Only one person needs to host a Server that all of the other Clients will connect to. Ventrilo is supported on different platforms as well ranging from Microsoft Windows to Apple Macintosh and Linux.
