Sharon asked who (or what) might be calling her phone number and then
not talking (or "tone"-ing").  My guess is that someone has published
her phone number incorrectly as a FAX number.  When fax machines
initiate a call, they first *listen* for a faxmodem tone from the line
they have called.  If no tone is heard, they just hang up.  (I think.)

So, Sharon -- you might try plugging in a fax machine into your line
during the periods when you receive these mystery calls.  If a fax
comes through, you'll be able to track down the company who published
your number as their fax number.
