Spoofed number.  The first digit of the exchange is never a "0" or a "1."

Getting calls from this number from people with horrible accent, claiming to be from the United Kingdom and asking for the CFO.  I keep putting them into voice mail.  One of the last calls I began laughing as the "accent" was SO BAD.  She asked me why I was laughing and I told her I knew this was a scam/marketing call.  Now get the calls and when I answer, no one will talk, just silence.  Definitely a scam.

Always call, but never leave a message. So annoying because they call all hours of the day - even at 5am!
