There has been a little discussion of this topic on the
asterisk-security list somewhat recently.
You may want to look at the message archive from August (
http://lists.digium.com/pipermail/asterisk-security/2005-August/thread.html
) as well as the one from September.

Hope this offers a little help; as someone mentioned, not much
documentation is out there.
