I just recieved a call and I didn't know who it was, so I didn't answer it.  They left no message either.

got a call on my cell, which by the way is on the do not call list.  no message left, but I get several calls from various Florida are codes with area code ---, followed by 000 - then 4 diget number.  Am tired of getting calls like this and no message to boot.

Have been receiving calls from 407-000-8537, 407-000-1639 & 305-000-1639.  They don't leave a message.  Asked for me by name when my wife picked up and wouldn't talk to her.  I am unlisted and on federal do not call registry.

Also got a call from this same number (305) 000-9957, on my cell while I was sleeping and no message. I'm on the do not call list as well. Got another call from overseas about 3 weeks ago and was also someone trying to sell something. Best thing to do if you don't know the number since there's so many scammers out there - don't answer your cell phone. Also saves your minutes if you have limited ones. ;) If they are constantly calling your phone, and have said that they're selling something, go to the do not call registry online and make a formal complaint. The more complaints about this number, the sooner we all don't have to get them.

Just got a call from 305-000-9957 and pressed nine trying to get to a live person, but it just kept ringing.  I am on a "do not call registry" too.  If you are on the registry, go to www.donotcallregistry.com and file a complaint; I just did.  I know filing a complaint works because I have had to do it with a couple of other telemarketers and the calls stop.  They get fined everytime they are caught so be sure to file a complaint.  It only takes about 2 minutes to do so.
