Free software RaidCall is created for quality voice communication with minimum time delay for professional gamers. It is designed for online games (eg: FPS, MMORPG), which require the participation of players in the team with a group communication,  for coordination of actions. Having established RaidCall, the user does not have any more to rent a server or install it by himself.


RaidCall uses a model of “client-server” for data transmission. The program sends data from the user to the server, which forwards it to other users on the channel. This sharply reduces the need for wider data channels, as the server supports for each channel near 1,000 slots. But Skype uses p2p for data transmission, and this requires from the user  the wide data channel.
