i got a call from this number this morning also... at about 9am (pacific standard time). The number showed up as +4072070820 on my cell phone. I just tried calling the number back (hiding my number from them, of course!) and I got some recording saying something about how all lines to the international number that i was trying to call were busy... or something to that affect. so bizzare.
My land-line phone rang at 11:58 am today with +407-207-0820 on call id. Since I didn't recognize the number and was trying to sleep, I did not answer. When I got up, I did call back and only got a fast busy signal. My only concern is that I WAS in the Orlando area 2 weeks ago for 8 days. After reading all of these posts, I am hoping that it is only coincidence that my number was called. I, too, am on the DNC list.
