Deem all incoming calls as 100% scams, until they are proved not so.
With mobile phones, its quite easy to block out scam calls, esp if they use the same number, but with home phones, I find it harder to block.
What ever Splash is, all about.
My hands free shows up that one in a while.
Have a relo that lives in Glasgow, so a 44 does show up, she uses a newsagency in the Scotland, sometimes not the same one, so can't block on the home phone, not that I know how to, so assume all incoming calls are scams, firstly.
Also, I now answer with "Namaskar ji", have had a few family friends complain about me saying that, thinking its a wrong number.
But it does put off the scammers, a bit.
The no noise/sound on the other end calls used to scare me, not even a click, esp when its shows as a "private number", but now, I don't answer those "private numbers" anymore.
""Namaskar scammer ji, you can podah"....
