E2E encryption for 1 to 1 calls

My first post. Please be gentle.

If install Jitsi Meet (per tutorial) on my own VPS and use it SOLELY for 1 to 1 video calls will the video call be encrypted?

Thank you!

rhat’s the default behaviour. If if it is what you want there is no need to install it since the public instance use E2E for one-on-one communications. The users may have to check that E2E is effectively active in the UI since if direct communication fails there is a fallback on the server.
