<div>VoicePulse claims to have developed a very sophisticated voip fraud detection system that it uses. They say their plans are to possibly sell this to other voip providers in the future.</div>

<br>make administration as simple as possible, it should be totally open for<br>anyone to view the records. However this also includes the people you<br>are trying to block.<br><br>I wanted to state this as it may be of concern to some, however I do not
<br>believe it will be that big of a problem since email-RBLs operate the<br>same way ... However with that said, a clever fraudster could scan the<br>DB for numbers they know they can profit off calling but arent listed
<br>then make a massive play against them in a very short amount of time.<br><br>This would be similar to the email spammers who will register new domain<br>names (and let them go unused after no more than 3 days), get zombies,
<br>do whatever.. infact after one of the largest known zombie networks was<br>taken down and the commander of that arrested many many of the 3 day<br>spam domains suddenly halted (not all but a large percentage).<br><br>
people will always try to figure ways through a system, so you cant<br>really rely on just one, however with email who just uses a RBL? who<br>uses just a spam filter without looking up stuff from distributed<br>databases? Most people use a combination of things, and perhaps this
<br>brings a marketing idea to light for someone who wants to write code<br>(either free, support for a fee, or total commercial). Fraud analysis<br>software, especially something that would integrate in realtime with<br>
asterisk (and possibly other platforms).<br><br>I happen to know that there are many companies that already do this for<br>the pbx world, I happen to have worked with one long ago in a galaxy far<br>away (ok it was new jersey but still :) I know they were always busy,
<br>which implies that people were buying, so this may be a new product<br>offering that someone could use to either get their name out there by<br>way of free code or make money or in redhat style both.<br><br>just a thought
