Recommendations for video call/conferencing server on OpenBSD?

Hi all,

with more and more colleagues and friends sitting at home, I'm
considering installing some video call/conferencing software on my
existing OpenBSD server.

I currently have Nextcloud installed on that server, so the easiest
option was the Nexcloud Talk plugin, which I'm playing with now.

Nonetheless, I'd be curious about what others use/recommend for video
calls/conferencing - any suggestions?

Thanks in advance,

Thomas
