Since the CLID said "WIRELESS CALLER" and the number is local, I picked up and said "hello". I immediately received a recording that started out by saying "Congratulations, you have just won a free cruise". I immediately hung up the phone. 95% of the time I don't answer or pick up the call and hang up immediately. Since I live in the ATL area, and since it looked like a cell phone - all I can say is they got me on that one!
Just got my first call on my cell phone from this number. Didn't answer since it's from area code 404, a known ILLEGAL telemarketing area code. Added the number to my PhoneTray software for the landline.
More likely than not a telemarketer for the credit card interest rate reduction SCAM.
IF YOU DON'T KNOW - DON'T ANSWER! If you do answer, don't press any buttons, just disconnect. If there was a pre-recorded message - REPORT IT TO DNC/FCC.
