[VoiceOps] Toll Fraud

[Nick Vermeer]

I'd like tap the collective knowledge here for some fraud prevention and detection resources.

Anyone have any information they can share on common fraudulent calls (i.e. Countries and associated digit strings)
What metrics have worked best to match to detect fraud before it becomes a significant cost?
What platforms have people used to analyze the raw data?

Links or RTFM pointers appreciated :).
