Video bandwidth and a Digital Ocean droplet?

Was thinking about getting a Digital Ocean droplet to run a Rocket Chat server - and I wanted to enable the video conferencing between participants - as far as the bandwidth for that goes - are the users connected directly to each other for the bandwidth or would everything run through the server and count against it’s bandwidth utilization? Thanks a lot!!!

Video conferencing is just a link/integration with an external provider. In this case It won’t use any of your own bandwidth, unless you want to host Jitsi yourself
