Can an incoming-call blocking-feature be added to home and wireless phones?
I'm tired of getting calls from a person named Michelle at the number, 661-***-****, who, every time she calls me, tries to sell me, first, a lottery ticket, and, then, diabetes medical-care equipment. I have told her repeatedly that I don't even have diabetes. Therefore, I want to keep her from calling me. AT&T told me, however, that there is no feature available for blocking any incoming calls. Unfortunately, the Call-Blocking feature applies only to outgoing calls. Can an incoming-call blocking-feature be added to home and wireless phones?
