We often use Ventrilo server when we play dota.Its much more easier with it.
About:
Version 3.0.0 introduces more user control of how the main window is displayed. You can turn on and off the title bar, display the large buttons on the right or switch to toolbar mode with icons on the top to maximize the usable width of the window. Extended mode which hides the User Name, Server and Bindings options. Turn on and off grid lines in the user list window. You can also customize the user list window icons and toolbar icons.
All of these changes still keep the most commonly used features at your finger tips by means of a single click of the mouse. No need to navigate clunky multi-stage menu options just send a comment to the other users.
