caller id says unknown

Same thing here except when I call back says its been disconected.

Getting same thing here. Says disconnected when I call it back. Called provider, and they couldn't come up with an answer. Done search on it and got lat and long coordinates. Went to GPS and got pinpoint map of location. It's on Johnston St, in between 2nd and 4th ave. It appears to be a business, but can't figure out which one.

Applied in wrong post, lol. I'm getting the same message from this number. They leave no message. Called back within 20 minutes and it says it's disconnected. Got a call on 10-11, and 10-12.

Get a call from this number 2563536468 Decatur,AL every night between 6-8pm. Won't leave a message. When I finally get em on the phone, I'll post the name of that "roofing and siding company" LLT referred to..

I got another call again, around 5:30pm. A call every day this week. They didn't hang up when my answering machine picked it up, I overheard someone saying something about "putting it on a machine before they get it". Not sure what that was,

Rings I Answer. and nothing..  No one says a thing..
