I see they tried to "call bomb" me yesterday afternoon.  They called 6 times in the same minute hoping to overwhelm Verizon's simultaneous ring feature to Nomorobo.

It didn't work :).

Didn't pick up. No message.

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 service. I've called AT&T months ago, as the Nomorobo.com page suggested, to request they help stop spam calls with this, but 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!
SO, I decided to use AT&T's call forwarding service to make AT&T understand the problem a little better and I suggest others do the same.  
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'm hoping if they start to get the same number of spam calls I get - they'll decide it's worth stopping the problem.

This is the scam contractors from Paradise Home Builders. Morons call every day from a different spoofed number. I wish they would build a prison so they could fit everybody from their boiler room operations into it. Would a legit business call from a spoofed number. These guys just want some credit info so they can do an identity theft with it.

Scammers are busy today.  Two blocked calls and 4 new numbers--and it's only noon.  Sigh.

These guys are a new piece of work, the trace is from Burbank CA. Spoofed name

I called back their number.  It is from "Contractors United"

Received call.  Didn't answer.  They didn't leave a message.
