Simple Voice Chat

Hi,
My team is working on a VR multiplayer game for arcades. The multiplayer sessions are player-hosted and are running on a local network using the advanced sessions system.
We need simple voice chat functionality: all players automatically in the same chat, always hear everyone (no push-to-speak), can be globally disabled or enabled. It should support a variety of VR headsets like Vive Pro, Valve Index, Quest 2, Focus 3 or WMR.
I’m struggling as there are a lot of different voice chat plugins, but they seem to bring a lot of additional functionality we don’t need or have requirements like using steam online system.
I would be really interested to hear from anyone who has experience in this area and can recommend a lightweight voice chat system that works with VR.
Thanks!

Use Voxel or
