I would make sure to get a security suite that checks for any of your identity being on the dark web. I was getting tons of these scammer calls and after checking with one of those suites I had TONS of my data where it wasn't supposed to be, such as my phone number being on tons of lists, sold to tons of businesses many of whom probably deal with scammers.
Today, I never give my real phone number to a business. I'll give a fake one, or one that I no longer use, or even a made-up one like 555-2659 because if a company really wants to contact you, it will be via email, text, or their app. they NEVER call. Many sell the numbers to data collectors who sell it to the lowest common denominator. After removing my data from those lists, changing passwords, and changing the phone number that I had on sites such as Google Play, Microsoft and Amazon to a fake number, those calls are few and far between.
Back in the 1990s, there used to be a little gadget you could put on your landline called TeleZAP that would listen for specific codes that scammer call centers used (sounds, clicks, delays, etc) and if it detected a scammer, they'd hear a very high pitched ear rape sound. I don't know how successful it was, but I loved to imagine the image of them whipping their headset off in sheer discomfort over it. I often wanted to use an air horn against a few back in the day as well.
There are exceptions though, many times your phone number is a reused number that someone else had. I had a home phone once that apparently must have belonged to a grandparent, since it got tons of automated calls from medical groups, insurance companies, and one from a school system that basically is recorded propaganda known as OneCall. Sadly, any attempts to stop those failed since calling them back (these were local comanies as well) was met with a recording of "this number does not accept incoming calls' so I was forced to change the phone number. In these cases, the calls were specifically coming in at a specific hour, day of week. There was no way to get rid of them, since answering them only had recordings, not real people, nor a method to tell the automated system to go frell itself.
