A lot of them phone me and ask for my wife by name "Can I speak to XYZ" - I usually reply "No" and end the call. Actually, for the last few calls I've not even been saying the "No".
I wonder, how this in affects modern software stack that have AI with the AI Call Screening which will ask questions, you can automatically identify certain dimensions: phone is active -- phone has a plan,-- phone is a Pixel or iPhone with a specific minimum model and OS ver ?
Then because of the leak side channel effect they can further future target calls such as coming from google about your problem with "your pixel 9 or 10?"
Maybe 3 or 4 of these a day <sigh>
