[VoiceOps] CLI sim testing

[David Knell]

A bit of thread drift here, but there's a whole industry doing just this
(albeit not ITSPs) for fraud (or toll bypass) detection.  Suppose an MNO
wants to detect SIM gateway usage on its network.  They'll have a bunch of
boxes just like those which Colin's after scattered around their network,
then the testing organisation goes and buys as many routes to that MNO as it
can.  They'll then make test calls down the various routes and see what CLIs
are presented at the terminating boxes.  If it's not the expected CLI, then
it's (probably) the CLI of a SIM being used in a gateway or that of a leaky
PABX.  Work backwards to the owner, bust them, rinse and repeat.  Given that
there is serious money at stake (MTN Ghana recently reported estimated
losses to SIM gateways of $9M in a 6 month period - that's about
$1/subscriber) this is well worth doing.

I don't know how big your operation is, but I have difficulty visualising an
ITSP whose revenue genuinely supports such an expensive venture for the
narrow purpose of catching merely one kind of marginal problem, where the
marginal utility of doing so would truly exceed the marginal cost.  Perhaps
you are the exception.
