Spam calls using caller ID "AA" have been targeting my number for several months, using a fairly large number of different phone numbers, including this one. That is, once I block one of them (like this number), after a little while I get called again with the same "AA" caller id but from a different number. This is one of the more annoying of this sort: I wish the phone company would shut them down.
Consider googling "call blockers". Many will allow blocking by CallerID, in addition to the displayed number.

The FTC and top communications companies are meeting, to determine what they can do to stop robocalls and other illegal calls. Here is a link to a frequently updated page, showing the history and progress of their initiatives:
