Call blocking seemed a great idea but recently fraudsters have started falsifying the number – technology here is beyond me but apparently it is possible to make a different number appear on the recipients phone.
Is faking the calling number really that recent in the UK? Seems hard to believe. It's been going on here (Canada) for some years for scam and junk calls making call blocking just about impossible. There were recent government initiatives making caller-id faking illegal (somewhat) but predictably it hasn't made an iota of difference.
Typically they fake the number using the callee's own local code so it looks like it's coming from someone local. Presumably they think the person is more likely to answer to that.
[ I continue to believe that the telephone company's computer knows the actual source of the call – at least as far as the originating country is concerned. Since virtually all of them are from outside the country (local laws make it risky from within Canada) it affords a means of fighting back if only I were allowed to choose which countries I'm willing to accept calls from. That should be my right since I pay for the service. ]
