VoIP Scanning

Interesting post on VoIP scanning...

What’s seems to be happening is that someone in France (from the IP address 82.234.27.188 from all the reports I’ve seen) is trying to find insecure SIP devices. They’re doing this by trying to make a call to 0033147310370, which appears to be a Fax machine or modem of some type in France. It’s a bit silly, actually, as ‘00′ isn’t a valid International code in lots of places - here in Australia, for example, the international dial prefix is ‘0011′, and in the US it’s ‘011′, so it’s always going to return a 404 here, no matter even if I do have a misconfigured device.
