I’d suggest looking into TeamSpeak, like others have mentioned. Trivial to self host, too.
Edit: to be clear, this would cover the voice call aspect of discord, not the chat channels and other community tools. While it’s can do text chat, it’s more of a side feature rather than core. I didn’t think it does images or video, but it’s been a hot minute.




I assume you mean unsolicited phone calls with this? I haven’t gotten any of those in about a decade, if not more. And those were isolated cases as well. We have laws against that sort of thing. It’s not been a problem for a very very long time (early 2000s or so).
