Okay, sorry.Teamspeak source code is the company. TeamSpeak is nothing without the single product they have. They don't have any other product.
Just to finalize, teamspeak 5 and teamspeak 3 are the exact same product. Teamspeak 5 is just a UI rework.
In that case i was mistaken by their "NEW Teamspeak" advertising policy but you get my point.
