Many modern phones are more fashion than use. Remember that Trimline phone, that with just a very slight pull on the cable it fell of what ever surface it was on, usually onto the floor, often disconnecting the call. Fashion accessory more that a useful phone.
Many portable type phones *(radio) are fine - if you can actually seen the keypad, in poor light or darkness. Many mobile phones are equally hard going. I find the low priced mobile - that doesn't sing or dance - the better ones.
Children were discouraged as far as I recall from using or answering the telephone. Usually the operator or 999 type of calls were the only ones permitted. But then in the times most of us speak of any form of telephone was purely for business or occasional use, people were not wedded to their ''phones.
* radio scanners can often listen in to 'phones that use radio frequencies.
