Dito (Synapse server), Element for desktop app and fruitphones, Shildichat for android (its lighter and has an adorable turtle as a mascot).

And seconding the voice coms, the VOIP relay server is a huge pain to set up, same with the registration page. My nerd herd hosts a few services that federated to share services and the admin group just issues people accounts.

TLDR: no… Were not using discord anymore, we have discord at home.
