Call waiting sounds on Win 10 mobile

[CMage]

I have a Lumia 950 with the latest OS version 10.0.15063.483. When I am on the phone and there is a secondary incoming call I get no voice notification. I checked all settings on the phone but I didnt find anything related to this issue. Any chance that at least a beep can be turned on so I got notified about the secondary incoming call?

On my 950, it's Settings->Extras->Network services. Then I select my SIM and it has "Call waiting" on or off. I don't know why this isn't in the regular phone section.
