Raidcall is a free, low-latency voice solution  for professional gamers.

Raidcall is designed for group communication while gaming, especially for games requiring tight teamwork such as FPS and MMORPG games. It can provide clear voice quality with extremely low latency, and there is no need to rent servers or set up a server by yourself. Raidcall makes group communication easier.

Raidcall uses the Client-Server Model to transfer data, rather than using the P2P Model such as Skype, which takes up more bandwidth from user. When user is talking in this Client-Server model, RaidCall sends one stream of data to the RaidCall server , then the server broadcasts it to other users in the same channel. So it requires very little bandwidth for voice communication and support more than 1000 slots per channel.
