How can we tell a button quail's sex it it is fully white?

With white quail I think you’ll have to wait til it lays an egg or does a boy thing (crow, courting with food, mating attempts).

No reddish or pink feathers around the vent?

With whites you can vent sex them or wait for behavioural traits.

So I am trying to get know how each sexes sound like.
I heard one of the whites making this kind of "laughing" sound (not my video):

So is this means it is a female or males also can do this?

Or males only do this?:

I think I’ve seen these videos before. The first one are silver males making growling noises and then that higher pitched chirp. Males sound like that and if you hear that then that’s a clear sign that it’s a male. Females are higher pitched and in my opinion they a bit more squeaky. (Maybe just mine) The second video are all males which of course is going to result in a lot of crowing and growling.
