Hi,
Y'all sound unfamiliar with this type of scam call. Don't be curious...it could cost you. Your best bet is to never answer calls from numbers you don't know.
Don't answer them, and don't 'play' with them, either. Would you open emails from people/businesses you don't know? Spam emails and phone calls wouldn't stand a chance of succeeding if people would just ignore them. If you  do respond, it will take alot longer for them to go away. They are 'selling' something that you don't want. If there was no financial incentive involved, they wouldn't be calling in the first place.
We are not idiots/children. I would like to think that we are all intelligent adults who have better things to do than to entertain intrusive, illegal phonecalls and emails.
Be careful, peeps...

Same here. I'm 707 with Verizon. Got a missed call from this number. Somebody please [***] them. Thank u

I'm with Verizon (714 area code). Didn't hear/didn't answer the call and will not call back.

I am with Sprint (714 area code).  I got a missed called from this #.  Possible this was a telemarketer or spam.

Got a call from this number on my land line.  Hung up before anyone could answer.  We're kind of glad we didn't pick up.
