TeamSpeak is software that allows people to talk to each other over the internet. It works equally well whether it's used for gaming, families staying in touch or inter-office communication. It has both client and server software, with the server able to host multiple client connections; thousands of people can use the system simultaneously with no compromise of service or quality.
Nearly a million gamers use TeamSpeak every day but it is also becoming popular for commercial use because of all of the useful features in the software. The scalable user permissions system is particularly handy for business use, allowing administrators to restrict access or grant it as needed. It can also be customized; the server has command line query capabilities that allow nearly limitless automation and scripting.
Another advantage of TeamSpeak is that it allows you to use a microphone and speakers instead of confining you to texting. If you do need to text, however, the ability is there and you may want to use it for URLs or complex information. Auto voice normalizing prevents your having to adjust your mic and voice quality is clear and consistent.
Other features include event driven voice announcements, a whisper function for privacy, password protected servers and channels, support of Gamevoice hardware and configurable hotkeys. TeamSpeak has minimal CPU and RAM requirements and is designed to work well with routers and firewalls. A local address book lets you connect to your favorite servers and a webserver list lets you find servers even if you don't know the IP address.
