Won't work. Caller ID is like the return address on an envelope. They can put any number there they want. See spoofcard.com for a commercial service that does this.
There have been a lot of calls offering "free" alarm systems in our community lately. It's the same message, but the caller ID is different every time.
And legislation? Where are you going to get the millions of dollars for lobbyists and campaign donations? That's what the industry spent to make sure the legislation we have is toothless, and that there's only a pittance in the budget for enforcement. Classic case of best regulation money can buy.
I know neighborhood watch is some sort of "are you home scam" however each time they call my home phone, within 3 minutes they call my cell phone which I have ot givenout to anyone. How are they connecting my home phone and my cell phones which I get from different companies?
Just a robocall to try selling a security system. I can't believe that enough people get suckered into this kind of call that it becomes profitable for them to stay in business. If no one would answer or ever buy a system from this type of caller, then the security "companies" would have to go out of business. But, nooooo, enough dingbats will say "yes" to them that it's still worthwhile to bother the entire country with their robocalls.
I'd like to start legislation to demand phone companies allow users to block a number before it rings your phone. Not an app or third party tool, something the phone companies are required to support. After X number of people report and block a number, that line is PERMANENTLY disconnected until the owner can prove its legit.
Why permanent? Then companies selling to these shams will eventually run out of numbers and figure out for themselves how to determine real uses of phone versus new scams.
