Who called from 4802437255

We just got a call from this number whereby the person/machine hung up when we answered and said, "Hello?"  An attempted return call to the number was met with only a message indicating the number's owner can not currently receive calls and the mailbox is full so no message can be left.

this is the second call I've rec'd from this unavailable magic jack customer, no idea who it is and they don't leave a message

Same thing,,, about 302p......no answer???  (5/3/2012-1500hs)

Got a call at 5 pm on May 3, 2012. I didn't answer because I didn't recognize the number. No message.

ditto, +1, spam?
