Wakeup Call

WAKEUP CALL….Yesterday my mother mentioned to me that she had gotten a couple of phone calls in the middle of the night recently. There was no one on the line, and all she heard was a series of beeps. Had I ever gotten a call like that?

Nope, not until now, anyway. Last night around 5 am the phone rang and I let the answering machine pick it up. All I heard was four high pitched beeps, each one about one second long and the entire call about 15 seconds long. Then it hung up.

Has anyone else gotten anything like this? Any idea what it was? Russian spying? Al-Qaeda psy warfare? A computer screwup from SBC?
