You are using which headset? A RJ11 connector, right? Not a 3.5mm jack

Can be some problem:
1) wrong headset (jack contacts - like Apple and Samsung have different contacts order).
2) in set menu can be programmed headset output assignment (not sure about 4028)

I think it won't work as you desire.
I do remember doing tests years ago and behavior was not the same as a headset. It is just an auxiliary audio exit.
You need to use a RJ11 one.
