Call came in (caller ID # 831-205-3097)
Recorded male voice said " This is (forgot his name talks very fast!) regarding your recent interest in our product."  Blah Blah Blah “Call me back at 909 259 26    Extension 871372572"  blah blah blah
"To hear that access number again, press 1"  (so I did because these numbers are messed up)
Instead of repeating it a recorded female voice says
“please state your name at the tone & Google voice will try to connect you”  
RIIIIIIIIIGHT.
I hung up.  We didn't have any interest in any product especially not one without a full call back phone number.
I guess the ploy here is to see if a person answers the phone so they can sell your number.  Like an idiot, I fell in and pressed 1.  DOH!

I found this on another site... "831-205 is not a valid prefix. If you are sure that you got a phone call from a
number beginning with this prefix, the caller may have 'spoofed' caller ID. © 2013

These calls have gotten out of control.
They are harassing & huge waste of time.  Time taken away from my work & my customers every time this cr@p comes in.
