I recall many years ago how my Mother worried about telephone calls which she answered but where the person had rung off or didn't speak. Even then cold sales calls were common and a considerable irritation. I think I disliked the people who made them to an irrational degree because they upset my Mother so much. She couldn't believe that sales people could be so thoughtless and so believed that they were trying to see if anyone was in the house so that they could burgle it.
Until recently I received many such calls each day on my landline. I could have barred international and withheld calls but many of my legitimate calls are international and some friends have withheld numbers.
Now I have solved the problem with one of the best gadgets that I have ever bought : the BT 8500 phone with Call Guardian which, for numbers not in your address book, enables you to hear who’s calling before you answer, and block those nuisance calls. As nuisance callers never leave a name and are often automated anyway they never even ring out. Brilliant.
