I receive this call on pretty much a daily basis. Caller ID reads "New York." Caller never leaves a message, so I know it is unimportant. Good information on the Do Not Call List from jc. Best defense against telemarketing is caller ID. I never answer a call I do not recognize or a caller that does not have the courtesy to leave a message.
Really? I find it VERY ironic that the very thing you claim (quoting massive figures of calls made, etc) is not possible..... Yet isn't that precisely what the NSA HAS BEEN DOING????? And the very reason they are building the data center in Utah? Think about that.... What you claim can not be done, HAS BEEN DONE. And more.
Start demanding the NSA - NATIONAL SECURITY AGENCY start ENFORCING (their job) the protections of the people of the United States as already established by law. As phones are now mostly (including cells) VOIP - That makes the harassment calls and especially the 'scam' calls originating from other countries subject to the ELECTRONIC TERRORISM protections.
If they're going to spend all that time spying on your calls -- make them tender the full trace records of every call connected with your number. Then demand they do their job and go after the terrorists attacking you. (They already claim they've gone after and protected US from so many terrorists already -- none of which they can name. Perhaps this would be something they'd look forward to do -- as these terrorists they COULD NAME OPENLY.)
Then again, why should they waste time protecting the people that fund their paycheck????
