Mr. Robert Mourik:

To some extent we can, but that is almost irrelevant. What we have been able to do is determine, to some extent, what technical loopholes they make use of. I will not go into too much detail, but part of the problem is that in the past the telephone system was a closed system. There was a monopoly in every country and it was based on technology that only a few trusted operators had access to. Nowadays, the telephone system is far more open and it is linked to the Internet, and there are newer standards. As a result of that, some fraudsters, many of whom are very well informed about what the technical capabilities are, can come up with those scam calls. What we are trying to do is to look at that to see what we can put in place in order to stop it.
