Who called from 4015191492

Several calls, no ID, no message.

Received call, but did not answer.  Caller hung up when answering machine kicked in.  Caller ID shows "NCO."

Keep getting calls from this #  401 519 1492 noted on CID.

This is in addition to the message I sent a second ago caller never leaves a message.

they kept calling me and i never answered. i finally called the number back and a girl answered the phone "yeah?". when i said "who is this?", she hung up.
