I just got one...

LOTS OF BACK ROUND NOISE.
WHEN I GET CALLS LIKE THIS, I SAY: "YOU HAVE REACHED A NUMBER THAT IS MONITORED BY THE ATTORNEY GENERAL FOR UNSOLICITED PHONE CALLS.  PRESS 1 TO BE SUED."

THEY ARE STILL CALLING.  RECEIVED A CALL ON 7/9/14 WITH THE SAME PATTERN.  DO NOT ANSWER AND LET IT GO TO VOICE MAIL, WHEN I LISTENED TO THE VOICE MAIL WAS A MESSAGE WITH FOOLISHNESS ON IT (LAUGHING AND JOKING IN THE BACKGROUND).

That's the same thing I get when I let Buckmasters solicitation calls roll to voicemail...just laughing, joking, office chair moving noises in the background, then it goes dead.  But those calls usually come out of Alabama, while this number appears to come from Ft. Myers, FL area.

Started receiving these calls this week. Have this app called CurrentCallerID. Placed them on CALL BLOCK. Now when it rings this wonderful app hang up on them. Priceless :-$
