they let phone ring, I let it go to answering machine as i don't recognize number on caller id and they will listen to your greeting then hang up-when you call back the number you get busy signal

I got 2 calls from the number on a Saturday, then 4 more on a monday  and so far another today (tuesday) from them.. never left a voicemail.. haven't bothered calling them back. I've never answered the call..Tried texting.. said it's not a mobile number and it can't be searched in a reverse lookup. I had problems with blocked numbers or numbers coming up 00000000000 before with similar behavior except one time I answered and they were talking but didn't realize I had answered. Hopefully it stops soon. How irritating, I'm not going to change my number just to get them to stop calling.

Received phone calls 1/3/09 at 1:14pm 1:27pm, 1/5/09 at 3:23pm 4:09pm 4:11pm 6:50pm and 1/6/09 at 2:24pm.
I have never answered any of the calls, I don't answer unknown numbers. They have never left a voicemail. I texted a response telling them to leave a message if they wish to reach me but I got an error message saying it was an invalid mobile number, and there were no search results when I searched the number on www.anywho.com/rl. I have not tried calling the number back.

Got a call from this number.  Phone Solicitor for a siding company, and the number was obtained via a contest my son entered so the Do Not Call list did not apply.

Yes, I have had an over abundance of calls from this number.  Today, I was finally available to answer the call and find out who has been so annoying.  The person on the other end said they were just calling around in our neighborhood to find out who needs a roof estimate.  I said we were not interested and to please take us off their calling list.  We are on the Do Not Call Registry and would appreciate them not to call us anymore.  This was at 1:22pm on 11/19/2012.  Then at 5:30pm I get another call from the same number.  Of all the nerve to call back again after I asked them not to call.
