What numbers is it that you push to on a land line phone that will connect you to the last call?

Question

I have a hang up caller and it keeps showing up caller unknown.

Answer 1

sometimes  *69  will do it,  but in most cases you just can't tell unless you keep him on the line long enough for the phone company to trace it

Answer 2

the *69 is good but they will charge you for it

Answer 3

*69 will get you the last person that called you

Answer 4

*69 (Star 69) in most areas. Unfortunately  not something that can be done everywhere. Good luck.
