Teamspeak

From 21stCenturyWarfare

TeamSpeak is Voice over IP program that allows users to speak on a chat channel with other users, much like a telephone conference call. A TeamSpeak user will often wear a headset with an integrated microphone. Users use the TeamSpeak client software to connect to a TeamSpeak server of their choice, from there they can join chat channels.

TeamSpeak has been used by 21st Century Warfare since it begun in 2003.
