Who called from 4012212121

Hang-up call when I called back the number was not in service

They just called me, but i didnt pick up. So when i called back the 1st time it was like the line was busy. I called back the second time and it had that cut off phone noise [[Doo-Doo-Dooo]]. Yea that one. So just dont bother picking up. Its a Rhode Island Area Code.

Got a call picked up the caller hung up,I called back and it said it wasn't in service

We also received a call in Tennessee from that number, but we missed it.  Glad to be able to check these types of worthless calls.

Just received a call from this number and they hung up.
