I was unfamiliar with teamspeak so out of curiosity I did a search and found a forum dedicated to Teamspeak. Specifically I hit the "FreeBSD guide to TeamSpeak2". The thread begins in 2003 (a little outdated), however it is quite lengthy, and the latest posts are from December of 07 where a fellow gives some tips and refers to his success on FreeBSD 6.2. Here is a link to the tail end of the thread:

Hope this helps
