New type of call going around this area.

Caller calls your number.  Caller ID shows the same area code and prefix as the phone it's calling.  The last four numbers are random. You answer it. It's a recorded message scam. You call the number back, you get a message stating that, "Incoming messages to this number have been blocked at subscriber's request. Same number will call you back till you block it. A few days later, same, thing, different set of digits for the last four numbers.
