These "silent calls" are a menace and I can imagine that they alarm elderly people especially if on their own. I can only suggest you turn your phone down or off overnight and ask any elderly relatives to use your mobile number which will display who is calling. Either that or caller display on your landline. Doesn't stop the phone waking you up though.
How much do you spend on yourself?
