SAME FOR ME. CALL AND HANG UP. NO ONE ON LINE. IF EVERYONE OF US WOULD PLUG THIS NUMBER INTO OUR FAX MACHINE AND TELL IT TO SEND A FAX WITH AS MANY RECALLS AS POSSIBLE, WE COULD STOP THEM. IF IT ANSWERS, WHICH IT WOULD, AND THE FAX MACHINE CAN'T SEND A FAX, IT WILL REDIAL THE NUMBER AS MANY TIMES AS YOUR MACHINE CAN BE PROGRAMED TO RECALL.. IF 40 OR 50 OF US WOULD DO THIS WHEN WE AREN'T GOING TO BE USING OUR PHONE WE COULD PUT THEM OUT OF BUSINESS.
