Thanks to package maintainer Adam Cécile the TeamSpeak 2 Client is present in the Debian repositories. Now, you can find packages including the latest version of the Linux client in the testing (etch) and unstable (sid) branches for architecture i386 as well as amd64 with 32-bit emulation. Debian users should now be able to install the package named teamspeak-client via aptitude or apt.

As TeamSpeak does not comply to the DFSG you should make sure to have Debians non-free archive in your package sources. If you have a look at the list of pending packages there will probably also be a package called teamspeak-server so we can hope to have an easy and comfortable installation for the server in the near future as well.
