This caller called 5 times in 15 minutes on my cell.
(314) 290-0000

Same thing. A friend who works for Cingular said it was someone trying to hack my phone.

This number keeps calling my cell and when I pick up it's is a fax machine noise. After a couple of calls to me I just ignored the calls so it cold go tovoicemail and then almost instantly the same thing from a different number 636-329-2100. They started calling at 7:45am on a Saturday.

4 TIMES TO MY OFFICE PHONE WHICH ROLLED TO MY CELL PHONE WITH ONLY A BEEP AT THE OTHER END.
WITHIN 3 MINUTES ALSO RECEIVED A CALL FROM 314.445.0000 - SAME BEEP
