[VoiceOps] Toll Fraud

[Simon Woodhead]

Hi Nick,
Great thread.

As a UK network I'd say +4487, +4490, +4470. These are UK
Premium/Special/Personal numbers and there is a tonne of international
traffic seeking these out. We continually advise customers not to touch it
unless it is organic UK retail traffic as there is no need for anyone
outside the UK to dial them. Traffic will typically be repeated 1-4 second
calls to the same number on which the perpetrator is receiving an
outpayment. They exploit the fact that there are hundreds of ranges, all
billed differently and that somebody somewhere in the supply chain might not
be current. We typically see those customers who ignore our advice
forgetting about the connection charge and making a whacking loss as a
consequence on what seemed too good to be true. We ourselves are exposed
when we don't keep up with tariff changes on established number ranges or,
dare I say it, we aren't informed. So, keep in mind, these are domestic
numbers and any international volume to them is fishy however good it looks.
