They have called my house a couple of times that I've noticed, they hang up when my answering machine comes on, and my caller ID reads, "NOT IN USE" - last call was at 11:39am today, 4-6-15.  Pretty strange...

Even more strange, the same name appeared on my caller ID, "NOT IN USE", only from a slightly different number, 720-204-2783, that call came in on 4-2-15 at 12:23pm.  Just tried calling both numbers from my blocked line. Figures that it rings off the hook with no answer.  On search, it lists a female by name Jamie Gibson, residing in Longmont, Colorado.  Anybody else out there getting these calls??

I get same type calls from Jamie Gibson Longmont CO but different number....(720) 204-2783.  Many calls and no messages...if Jamie needs something she can always leave a message....:)....ya listenin Jamie babe/dude?

I answered the phone the other night and she asked for my husband by his nickname but hung up when I handed him the  phone.  Sometimes caller ID says Jamie Gibson 720-204-2783 sometimes just 720-204-5542.  She's been calling for a month.  We have an answering machine she can leave a message from now on.  I'm not bothering to answer anymore.

I get the same calls from Jamie Gibson in Longmont, too.  I don't answer because I noticed after the first two missed calls that he/she never leaves a message and I don't answer calls from people who won't leave a message.  They're usually selling something....but it is getting annoying.
