My Caller ID shows they've called sporadically for 2 months.  Tonight answered and got an immediate hangup.  Only other thing I can find on this number is that it's a robo-dialer. I agree with that person, don't answer.

Female caller wanted my daughter but would not state why.

called our Unlisted number (which is also registered with the Do Not Call Registry, for all the good it does), a male asked for my daughter by her maiden name (which she hasn't used since marrying in 2007) and who hasn't lived here since 2005. Would not tell me how he got this number nor identify who he was or who he was representing.

Called my unlisted number and I got a hangup.  Not the first time this has happened with this number.
