Hey there @Kokapuk! So like a social deduction style game? Working with VOIP is different for every system, and the built in VOIP system doesn’t have a channels feature, you’d have to do a bit of C++ work to get it to do multiple channels. I have a reference on how to get it setup for a basic listen server, but if you’re using something like EOS I do believe there’s more features there and this developer has a couple of videos on the topic, including voice sessions with EOS.
