Tones disable in node asl

I would like to disable the tones that the asl simplex shari node gives when someone transmits via RF, they are useful to know the coverage just like the queue in a repeater, but I don’t know what parameters I have to change and where

Edit /etc/asterisk/rpt.conf and under your node find nounkey and set it like so:

nounkeyct = 1     ; Set to a 1 to eliminate courtesy tones and associated delays.
