Sound files

How can I install the new (other language) sound files?
Where can I find any tutorial?

I got this from PBX in a Flash® without Tears:

If you wish to use a different language other that the default American English that comes with Asterisk, there are a couple of ways that you can do but as this guide is for beginners, I will go the easiest method.
Create a subdirectory for the particular language (eg: ‘au’ for Australian English, ‘fr’ for French, ‘it’ for Italian etc.) in the /var/lib/asterisk/sounds directory, e.g. /var/lib/asterisk/sounds/au and send all your prompts sound files there. Also create the language directories in the digits, letters etc directories, and send the entire prompt files there.
Add the following line in the iax.conf and sip.conf configuration file under [general]. In zapata.conf configuration file the line should be added under [channels]. language=au ; (or fr, it or whichever language is installed)

You can go to asterisk to download.
