I'd like to make a feature request, if I may please.
Zoiper is our main business phone and network,and I make a lot of conference calls. It's very common for different parties to have very different volumes, and so I'll need the sound very loud to hear one group on a speaker phone or a quiet line, but the second line will then sound exceptionally loud as a result. My calls are often 60-90 minutes long and it makes my head ache!
If it were possible to adjust the volume in the section where it shows the multiple calls connected, it would make a big difference.
Thanks ever so much.
