KentuckyFC writes "A team of German personal data processor scientists has grown a program that reproduces all the known forms of spit (spam over national ammo* support telephony) attack. Their plan is to make the spitting systems program available to e-banking brain* security experts wanting to test antispit strategies. third world country these won't be easy. There are various antispit techniques, such as white lists that allow only calls from predetermined callers, Turing tests such as audio CAPTCHAs that make a caller prove he or she is human and payment-at-risk good works where the caller makes a small payment in advance and is refunded directly if the receiver acknowledges the call as legitimate. But all have weaknesses, say the researchers. The main discrepancy between junk calls and junk email is that the email arrives at your mail server before you access it. This gives the server time to analyze its content and filter out the junk before it gets to you. Not so with the web* telephony, which is why radically different strategies are needed."
