Caller left no message, just hung up.  Tried calling the number back but only heard a couple of "clicks", like someone picking up and then hanging up the telephone.  CID read:  Trenton, NJ.

Picked up no response most likely another telemarketing scammer

I just received a call from this no. on my job, no one answered, mystery caller I wonder if it was from Match.com?

Got a hang up on my cell phone from this number. If you don't leave a message you are not legit.

Drug/alcohol addiction hotline...my number was given to them by a friend or loved one.  Right.  Don't bother attempting to opt out - they keep calling from random numbers.
