There was a major upgrade to the conference calling about 6 months ago which took it from being "barely usable" to "almost as good as Zoom". It's different semantics to Discord in that it's classic conferencing rather than a voice channel, but it works well enough for the whole core Matrix team to use it basically constantly for remote collaboration.

The conferencing servers are currently in London however, so you may suffer from transatlantic traffic problems if you are elsewhere in the world.

Ah, thank you for the additional information. Is my grapevine information correct that more work will be done to improve video calls and screensharing in the coming months?

As an example of what could be improved, I do still encounter the occasional bug with call synchronization, the video stream of one of the sides not getting started on occasion and screensharing is hardly discoverable.

Good to know!
