Criminal TeleScammers calling to case and see if your home, to rob you.  Any home improvement scam you want to hear, they will tell you, when (if) they answer.  Call back, and it is a bogus number.  I am ont the Federal and CA Do Not Call Registries, calls coming from these criminals are illegal.

I always use my 2nd phone to dial an incoming unrecognized number. It came up not in service so after a man said hello I said " I need to tell you this call is being recorded" he responded by 'I don't care if you are recording this call and enjoy getting 50 calls a day, jerk' and hung up. Next time he calls I am going to set an appointment and get the salesman at my home.

Monday morning starts and this is my third call (all from different numbers) and I have already put in three entries today. Anyway didn't answer. They didn't leave a message.

jerk offs 3 rings & hang up.

Yet another call from 310-232-3232

didnt say anything....blocking

There is a way to sign up for a FREE service called nomorobo to stop these annoying robocalls. My problem is that my landline carrier, AT&T, currently doesn't support Nomorobo because they need to add the Simultaneous Ringing rejection capabilities to their LANDLINE service. I called AT&T months ago, as the Nomorobo.com page suggested, to request they help stop spam calls with this, but after wasting my time jumping through all of AT&T's automated hoops to reach a real person to speak with, I found out they don't seem to care and have no solutions of their own that worked (yes, I even paid extra for one of their products that was supped to help, of course... it didn't!) I suspect phone companies profit from these calls, as others have suggested, so they have no incentive to stop them, and just let us, the receivers of these harassing calls, suffer - and in some unfortunate cases - get scammed.

SO, I decided to use AT&T's call forwarding service to make AT&T understand the problem a little better.  
After I get a spam call, I enter it into my "call forwarding list" (*63). The number I have dialed in for the call forwarding is: AT&T (Traditional Landline) Customer Service 1-800-288-2020 (I had to use the number "one" in my entry). This way AT&T, who refuses to help stop this problem, will get the next spam call from this number (if it's repeated) instead of me.
I'm hoping if they start to get the same number of spam calls I get - they'll decide it's worth stopping the problem.

Another hangup call.  This means they are using a robodialer, and no one in their smelly, sweaty boiler room was available to pick up the call.  Robo dialers are illegal for telemarketers, but these creeps don't care.

keep calling no answer

These idiots call everyday, they never leave a message and if you do answer, they hang up on you.  I'm guessing more Scam/Spam telemarketers.  

Thank you so much!  Very grateful for you taking the time to post this information.

Blocked! :)

I am on the do not call list.  Someone called from this number saying they were a contractor on Angie's List and were calling people in the neighborhood to see if they were interested in home remodeling services now or in the future.  I said I was on the do not call list and they hung up.

BLOCKED

Panasonic - MENU > Caller List SELECT > Scroll down to number > SAVE > CALLBLOCK?  >  YES

Many phones have similar features.  Some you have to block via the phone company / cable company website.

My cellphone also has a list although it's not this easy to get the number on the list.

Another one bites the dust...  

CALIFORNIA and not in service.

Remodel company, I asked to please be removed from list.  He said no and was very rude.

Spoof number. Tried calling it back and get a non-working number

Received a call, nobody on the line and they hung up after about 15 seconds
