[VoiceOps] Fraud fun

[Spencer]

I'm not sure what your requirements are but, we recently blocked all non-ARIN IP space from reaching our registrars. We had something similar happen and this has essentially eliminated the fraudulent calls we saw.

Thanks,
 Spencer

Hi folks,
We have been hit twice in the past two days with calls to 011-252-XXXXXXXX (calls to Somalia I believe, and the originating IP is from Pakistan)

It's the same user each time, I think he had a weak password, but it cost us over $100, which isn't too bad (we catch it quick) but I'd like to get it closer to $0. :-)

Any good recommendations for IP ranges to block from incoming connections?

Thanks,
