Does it work on spoofed numbers?
"I bought some phones with call blocking/screening built in. Not had a single spam/scam call now in 6 months. I got some for my mum as she was getting half a dozen a day and now gets none.
Takes a few minutes to set up, and for new numbers it's a single press of either 1, 2 or 3 to allow screened call once, permanently or to deny/block entirely."
In the States the spam calls can display on caller ID a number that is not the number they are calling from, i.e., spam call purporting to be from Police Department, or with proper number displayed, but not actually calling from that number. Does this blocking work on the actual number or the displayed number?
