The expression "to talk by the phone" is correct and I'm pretty sure if you use "through" instead of "by" it makes sense as well, but what about this expression: •You never know what's gonna come THROUGH that door•
Could I use "by" in the expression (or sentence) from above? I know the word "by" has a lot of meanings but in this case, to me, it means "by the means of" so is this correct? I know it may not be that common but could it still be considered as correct?
It's like saying: Travel by car or Travel through car, to me both of these are ok but the first one is more common
