Another political robodialer...it will dial numbers even if the CALLER doesn't have an operator available to take the call! This type of calling should be made illegal, if they are calling you, they should be present on their end of the phone.
OK, we got numerous calls from this number, too. Sometimes 4 in a day!! I called back...listed as an invalid number when I called them back. Phone rang again, saw the number, picked up....it's the Republican Party!!! And since I got all this hassle....I HUNG UP ON THEM.
