Choose what apps mute all other sounds on VOIP call in Windows

Question

Is it possible for Windows 10 to choose what apps should mute all other sounds when I am on a VOIP call?

I know that Windows does it for Skype and games, but I use mostly SIP protocol programs like Zoiper or Jitsy. When using these, and when I make / receive a call, other sounds are never muted. I am usually listening to music simultaneously from a browser, and its annoying to have to manually lower the volume everytime I have to VOIP. Its even harder because I have to switch virtual desktops also to do it, because I keep work v.desktop away from the rest.

I've searched all over the windows control panel, and also googled around but couldn't find any options for this. Any recommendations?

Answer 1

It is not possible. The app have to make some system call so the OS will recognize it as a VoIP app and reduce the volume for all other apps. However I don't know on which API call this is relied on. I hope that somebody will answer this.
