re: #15 Anymouse

From the previous page:

The advantage of living in a town where our telephone book is one page.

My wife as librarian sent out a circular to everyone in town on this subject (since we have many elderly people here) on how to recognise spoofed numbers.

Every allocated number in town’s last four digits are 01xx (government and business), or 9xxx (residences). Any other number is spoofed.

FYI: That is not actually correct. Your own phone number can be spoofed.
