TeamSpeak is an online voice communication software based on VoIP. It differs from the classic phone in that virtually an unlimited number of users can speak at the same time. It looks like a radio, which can simultaneously use multiple channels and has the convenience of military style radios. Programs of this type are designed primarily for gamers, but can be used wherever voice and coordination of a large group of people is necessary. It is worth noting that these services can be implemented within the very gaming applications where interaction between participants are essential for game play.
