Second call from this number. No message left on either call. I don't recognize either the number or the Caller ID.

I also received my second call from this number today. No caller ID other than "Ramona, CA". I won't answer calls unless I know who they're from and I want to talk to them. This call didn't ring through since I blocked them on their first call several days ago.

Called my DNC home line. No message. Blocked the number.

They hung up after third ring.  Never went to answering machine.
