TeamSpeak is a VOIP (voice-over-Internet protocol) program that allows users to connect to a single computer and talk with one another over the Internet much like a conference call.
The computer that TeamSpeak users connect to is referred to as a server. TeamSpeak servers can either be rented for a monthly price or hosted on your local machine for free for noncommercial purposes.
Download the TeamSpeak server application from the official TeamSpeak downloads page. The download link you choose will be based on the type of computer you have (Mac or PC). The download you choose will also be contingent on which operating system you run on your machine; Windows or Linux and 32- or 64-bit.
Read the TeamSpeak terms and conditions. If you agree to the conditions, click "I agree" at the bottom of the page to proceed. Once you agree, a download prompt will ask you to "Open," "Save," or "Cancel." Select "Save" and choose a file path for the TeamSpeak server, then click "Save" to initiate the download.
Right click the zipped TeamSpeak server folder and extract it.
Open the unzipped TeamSpeak server folder, and double-click on the teamspeak server application icon. When the server starts for the first time, it will display an administrator user name and password for you. Write this down, as it will only be displayed one time and is very important.
Note that the server application name will vary depending on which version you downloaded. For example, if you downloaded the Windows 32-bit version of the TeamSpeak server, then the name of the application would be "ts3server_win32."
Open your TeamSpeak Client while the server application is still running, and click "connections," then select "connect."
Input your local IP address in the text field labeld "address," keep the default port "9987," create a nickname and leave the password text field empty.
Click "Connect" to confirm, and you will be connected to your TeamSpeak server.
Open the Teamspeak server file and double click the "Logs" folder.
Locate the first server log file, which should look like "ts3server_thedate_random numbers," and open it.
Right click, and copy the token number located in the second block of text starting toward the left.
The token number should look something like this: "token=63SMd5svPAmJAJ37DeSpeGw+VMLJvmvmOGlrM+lk." Make sure to only copy the numbers and letters that follow the word "token=."
Return to your TeamSpeak client, and click "Permissions," and select "Use Token." Right click in the text field that appears and select paste.
Click "OK" to confirm, and you will be granted administrator rights to your server.
In order for other clients to connect to your server, make sure that ports "UDP 9987," "TCP 30033" and "TCP 10011" are open. If you are behind a router, you will have to use port forwarding to open the ports.
Firewalls and antivirus software are important, but can interfere with incoming connections to your server, so make sure that you adjust them to make exclusions for the ports "UDP 9987," "TCP 30033" and "TCP 10011."
