Just a recommendation from myself, for gamers wanting to use a free Teamspeak server that is solely dedicated to gamers from all regions.
Its called "GamersArray" and is open for use by people wishing to chat with friends/new people in different types of game play.
If you have any questions leave a reply in the thread. I am currently using this teamspeak server so I should be able to help you out.
The details for the Teamspeak server are below.
SERVER NAME - GamersArray
Server ADDRESS - voice.helpcomponline.com:9111
Server Website MyExtraneous
please note, I do not own this teamspeak or have partnership. I am just a client.
