Hopefully you are in a network that allows P2P! Then STUN just works and you can use any of the public servers (CloudFlare, Google, Twilio...)
Running your own TURN server would be trivial also. I have been tempted for a long time to make a 'TURN in a Box' that does autoconfig so people can run it easily on Hetzner/AWS
