No one spoke.

Called, I answered, they hung up

Caller ID: UNKNOWN NAME. They called. No message.

This had to be a robo-call. Called at 9:17 AM. Then called at 9:18 AM. All these blasted robo-calls are **not*8 covered by the Do Not Call  policy. Those who complain that the DNC does not work are sadly mistaken. If it didn't exist, we would be inundated with all kinds of targeted calls from legitimate manufacturers, etc. Be thankful that the DNC system is in place and DO NOT ANSWER if a calling number is not one you know or recognize. Let the answering machine take a message--if any. All these robo-calls are annoying but not answering them is the best policy. Ignore them. Patience....don't let the robo-callers get under your skins.

Didn't recognize the number.....never answer these
