calls but don't leave message.every day.some time 2 or 3 times.don't know the munber.i think it recorder massage.

Caller ID is "CLOSTER NJ" ; no VM left- didn't even see it until going back a day or so in my call history....
Have been seeing this interspersed with calls for "LAS VEGAS NV"  over the last month, at least one or two a week.

Robocaller and maybe a scam or spoof....

Calling back from an anonymous phone got a computerized message that itself a spoof- it tries to make you think that there is someone at an extension "3208" and that you can leave them a VM- not only does it not do that, the system would imply that you can reach an operator to speak to- instead the message is that the number you have reached is no longer in service and it hangs up.

Hardly a legit attempt to get a new customer or create a business relationship; are there really businesses  out there trying to use this method to get real work?  Tsk, tsk...

call from 201-297-4369, hold message, no one at the extension

Received today Wednesday, February, 2012 at 15:31. Did not leave any message.

calls daily at different times  

I picked up just now--a recording is trying to contact someone--not me--but someone I knew several years ago who probably owes money.
