This number called, just once so far, and left a voice message.
Voice message sounds like it is French or Spanish..

Got call from this number last night and left a message which was a recording that said "security check". I called back and got message that the number I was trying to reach was out of service. Area code is Los Angeles but I don't believe that the phone company gives out the number 000-0000 so I'm thinking it is some kind of phone hacker/scam.

Been getting calls on my cell phone from 213-000-0000. I don't pick and just let it ring to conserve my minutes.

This person called asking for someone in the office who wasn't in.  Thinking it was a solicitation I asked to be removed from their list and she said "NO".  I asked where she was calling from and she said from the 'governor's office', seeing that she refused to remove us from her list I hung up.

Got the call at 8:32AM, dead air, then 2 minutes later, I got another call from Anonymous 0 doing the Nigerian prince scam!!
