A terse, altered "Hello" is all I say. Sometimes I don't say anything. Most humans would wait a few seconds then prompt with "...Hello?", whereas bots tend to hang up after ~2s silence
When it is a human scam caller, what I sometimes do is to say "Hello" and then, when they start talking, and I can already guess they are full of shit, I act as if I am not hearing them properly and say "Hello?? Heeellooo? Hello?" Then they hang up lol.
