1) you mess up your extensions.conf and some bozo - on purpose or otherwise - runs up some insane bill on that nice little donated phone line - handle this by doing REALLY specific exten lines and you should be fairly OK
2) abuse of the extreme types noted in Duane's original reply - no technological solution for this one beyond making sure your outbound caller-id is not sent (a darn good idea in any case but no guarantees it will stop any more than a casual attempt to 'trace' the call) - and make sure you keep your asterisk CDR logs...
