Complaint filed with FTC, and the Illinois and Oregon State Attorney General's.

Good for you, if enough people keep up the pressure the government will have to take this seriously.
What To Do When You Get an Illegal Robocall; http://www.ftc.gov/bcp/edu/microsites/robocalls
1.    Hang Up. Do not press 1 or any other numbers to get off the list.
2.    Consider blocking the number
3.    Report it at http://www.fcc.gov/complaints
4.    Report it at https://www.ftccomplaintassistant.gov
5.    People should continually file complaints with their Attorney Generals office.
Register your phone numbers online at http://www.donotcall.gov or call (888) 382-1222 (must call from # you want removed).

I have greatly reduced the number of calls to my cell phones by going to my carriers website (Verizon) and they allow me to block up to 5 numbers for 90 days. Since these scum change numbers every 30 I have had a very peaceful time. Call me once shame on you, call me twice shame on me. I also put it in my contacts list under Scum Suckers and assign it NO ring tone so at least after the first call they won't bother me anymore (I have filled all of the numbers in each and am up to Scum Sucker 47 now). This is only a whack-a-mole solution however it is the only one I can offer.

The criminals behind this operation aren't going to pay attention to you asking to be removed from their list. Their calls cost them nothing and they can make thousands of them a day so they have no intention of ever removing someone. When you press a key to talk to them all that is accomplished is to verify that they have a working number. So what is their reason to continue calling even though they know you won't fall for their scam?
It's called the CNAM revenue-sharing program. Here is the explanation direct from the website of one of these operations.    http://www.telephonemanagement.net
"Every day your company makes thousands of outbound phone calls. Every one of those calls generates revenue for many companies, why not yours?
Our CNAM revenue-sharing program helps you make money every time a Caller ID request is made by a phone carrier. A high-traffic call center can lose hundreds to thousands of dollars a day to phone carriers by allowing them to charge for access to your own data."

You can now see why the criminals keep calling even though they know you won't fall for their scam. If someone does make the mistake of answering the phone and falling for their con then it is just icing on the cake for them. These people are the lowest form of filth on this planet.
Write your Congressmen and Senators. We need CRIMINAL penalties against the companies that are profiting from these calls. Follow the money, slap them in prison, no one left to outsource to overseas boiler rooms, problem solved. The government needs to go after them using the RICO act. That will be the only effective means of dealing with this.
Here is an excellent blog site that I found that explains how one company is getting away with this activity.

I am a representative of AnswerNet, one of the companies that have been mentioned in the complaints on this website. The calls that the complainers have been receiving are NOT from our company. AnswerNet appears to be a victim of caller ID “spoofing.” Caller ID spoofing is the ability to change the telephone number that appears on a caller ID display when they receive a phone call. Many scam artists deliberately falsify their telephone number to disguise the true identity of the calling party in an effort to present fraudulent offers of a variety of goods or services.

AnswerNet is a full service call center provider that produces telemarketing campaigns on behalf of our clients. We do not engage in direct-to-consumer calling programs for AnswerNet itself. AnswerNet follows strict FCC guidelines, and scrubs all calling lists against the National Do Not Call Registry (DNC). Additionally, our model is business-to-business only.

AnswerNet does want to assure consumers that we are doing our best to correct this situation. Please continue to contact the FCC when called by these individuals.

Should you wish to contact our corporate office about this matter, please call 800-411-5777 and you will be directed to the Communications department.
