unknown caller from little rock, arkansas - probably a collection agency ;-)
btw: they don't like to leave messages on your answering machine, so if you don't answer, they will just keep calling back until they get a live human.
fyi: i will not be answering that call!  :-)

501-353-0992 i just called that number and it says the number you have dialed is not in service...im looking at my phone logs online and it says this number was dialed 4 times for a total of 28 mins. but nobody was home but me and i didnt make any phone calls...and this number never called my house....im a little freaked....maybe its a mistake or maybe its from other telemarketers ive been getting calls from....

Same thing happened to me. I just got Comcast Digital phone and I looked at the "dialed" log and saw 5 calls to that number. We do NOT call back numbers we don't recognize. I wondering what's going on.
