Road Top Headunit - Phone volume at a call too low

I replaced the NTG 4.7 display in my S212 with a Road Top new display unit. When I'm using CarPlay and make a call the volume of the voices are similar lower compared to music and Siri itself or other audio output.

How can I make the voide more louder so I don't have to turn up the system volume at all (and turn the volume down again so my ears don't explode!). I tried several settings and adjusted "Telefon" to the max here Road Top settings ... is there a hint? Using the volume buttons on steering whele or NTG itself doesn't change anything ...
