Question about Canon FAXPHONE B640 Plain Paper Bubblejet
Try plugging a phone, with a different cord, to the wall outlet the B640 is using. Do you hear a dial tone? If you do, replace the existing phone cord going to your B640. Now press the "hook" button on your B640. Do you hear a dial tone? If you answered yes, what messages are you seeing displayed now? Once I know your answer, we can take it from there.
