called today, no one there, but odd buzzing noise on phone.

unknown.  broke the connection on the second ring.  I don't answer unrecognized calls.

CID: Jacksonville, Fl. Left no message, so it can't be important.

I got a call at 12:19 pm on June 9, 2017, about the time telemarketers start calling.  The caller did not leave a message even though my answering machine was on.  My caller ID said, "Out of area."  Why would any legitimate business caller use 'out of area' for a caller ID?  Who's going to answer a phone with 'out of area' for an ID?  No one, unless they're stupid.  Don't all legitimate businesses use their real name for their caller ID?  I would think so.  If you're running a legitimate business don't you want to let your customers who you are?
