Tell 'em you have a MAC, that stops them in their tracks every time, or that you don't have a computer.
I'm in New Zealand and I had a flood of about 12-15 calls over a short period but they have since virtually stopped. The last was a few weeks back, a woman with the usual accent and when I told her I didn't have a computer she just hung up.
Incidentally, whistle blowing is no more than an irritant, a phone cannot transfer that volume and you are more likely to hurt your own ears.
Cheers
Billy
