My caller ID says this number is unavailable.  I haven't answered the phone but they've been calling every 5 to 10 min.  Since I have caller ID, I will not answer.

Same here. Caller ID just says RHODE ISLAND. I don't answer any phone numbers I don't recognize. Been calling here at least 5 times a day. Won't leave a message.

Finally gave in and answered a call from this number.  The lady who answered said she was with "9to5" and apparently all she was calling for was to urge us to vote in the upcoming election to support working women's issues, or something like that.  She couldn't name any specific issues we should be concerned about or anything in our state that her group was promoting or against.  From other posts I've seen about calls from this number, my guess is that it is used by a company that makes phone calls for any number of organizations and that the other calls we've received were probably regarding completely different issues that are important in the upcoming elections.  We've blocked the number now so hopefully that will cut down on at least some of the calls we're getting these days!

Thanks Dee.
I was getting calls from this number (Unavailable) every 5-10 minutes last Wed. and I almost gave in and answered just to tell them to stop calling.

Yes, I finally gave in and answered too. Political robocall. You just answer one question: if you'll be mailing in your ballot or dropping it off? If you tell the person, then they stop calling you.
