Caller ID is the best! We answer NO calls that are not identified, or from organizations, or people we do not know. The call rolls over to the answering machine...If it were important, they'd leave a message. Usually the "Robo" message has to do with lowering my interest rates on credit cards, (we don't have any balances) or, they can refinance our mortgage...(don't have one of those either!!) DH has diabetes, and in the beginning we got tons of those calls, and lots of mailings also. Not so much now...think they gave up!!
