Received call from this number on my cell. Let it go to voicemail. No message left. Returned call several minutes later and got a recording saying number was not in service.  Now blocked.

Funny thing... a few minutes after I posted this I got another call.  CallerID said: +140830221396.  That's the same number with a "6" on the end.  However, it's an invalid North American phone number.  Phone companies should be smart enough to automatically block these kinds of calls (obviously spoofed numbers).  Blocked this one as well.
