I get these calls all the time. It seems the national DO NOT CALL registries do not work. Anytime I have to register for anything where you HAVE to give a phone number, I give my cell phone. All my friends/family/business associates are in my contacts so when they call they come up by name on the caller ID, this way when a strange number or PRIVATE NUMBER comes up, I do not answer (no answer - no minutes either) and no one has my home phone except those I choose to have it. No telemarketers get it either.
