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. -- Steve Elias -- eli@chipcom.com (for Chipcom / networking related mail) -- eli@spdcc.com (for metroboston email2fax and personal mail) -- voice mail: 617 932 5598 -- work phone: 617 890 6844
