My grandfather always uses his caller ID, if he doesn’t recognise the number, he opens with " SAS, do you want a fight?"
Personally, I just hand the phone to my four year old 
I am usually polite and say" no thanks not interest" but every once in a while one of them will really piss me off after I say no thanks and ask to talk to my husband. Then all hell breaks lose LOL
