I believe this is from the American Bar Association (ABA). They have been calling my house repeatedly at about the same time every year for the past four years. They use the 312 area code with a 219 prefix. They will call about 20-30 times over a 3 month period and then stop, but then a year later it happens all over again. I have probably answered about 50 times from all of their numbers, but there is never anyone on the other end and nobody ever leaves a message. I think they are trying to contact a lawyer.
