Editor—I would like to bring a recent experience to the attention of British doctors who might be lagging behind with BT's technology. A patient tried to contact me while I was at home. Naturally, the hospital refused to give my home telephone number but rang me requesting that I phone the patient. I immediately did so, neglecting to prefix his number with 141. Later that day my son was upset to answer the phone to the same patient, who had presumably traced my home number by dialling 1471, which reveals the number of the last caller; had I prefixed the number with 141 my number would have been withheld.
After this, I contacted BT (on 0800 661441) and arranged that my number is permanently blocked unless I specifically unblock it by prefixing a call with 1470. I would recommend this simple procedure to others.
