Google telezapper. $19.99. Or place the sit tones as the first thing on your
answering machine.
IF you have a caller ID compliant modem, there is also software that will
recognize out of area calls and play the SIT tones for you.

There are also gadgets that intercepts all phone calls and the caller has to
enter in a password to be let thru.
IF you didnt give out the password, tough.

I have had it with being polite to this company. I have asked them to
put me on the do not call list. I have my number on the national do
not call list. I have reported the number to web site. They still
call.

At first, they were calling with a number that would come up on the
caller ID. Now they call with unknown caller. It is from some
consumer credit company. They give a recorded message and press 1 to
find out how to lower your rates.

I wait until an operator answers. When I politely ask to be put on
the do not call list they hang up. One guy was polite, and said he
would add my number to the no call list.

They still call.
