Dan York gives a great Podcast (delivered here in a powerpoint presentation) about VoIP Security. It is an enjoyable anecdotal talk, where he sets up a story and tells the pitfalls that can begall an unsuspecting ’sysadmin steve’ who inherits a VoIP system. Really, the intent here is that there are a number of potential security holes in VoIP that at the very least you need to be aware of. If your phone calls and what  you say don’t need to be ‘private’ then you probably don’t need to worry too much!
