Matrix supports voice and video integration out of the box, as does Zulip.
I think voice chat is very popular with gaming discord users, not so much with software projects anyway.
In any case, it is so simple to just send a link to an open jitsi instance on any platform that it isn't that big of a deal if you do that once every full moon.
Unable to decrypt: The sender's device has not sent us the keys for this message.
It's very unfortunate that the entire Matrix ecosystem seems to be funded by people who want to build private branded messaging systems for enterprise and government and other users aren't the target audience anymore.
The Matrix Foundation tries to fund itself philanthropically by selling sponsorship and memberships at matrix.org/support, but it doesn’t remotely cover the full dev costs.
So there is absolutely no alternative but a) ensure the wider independent FOSS ecosystem can build general purpose apps (which they can and do - eg Cinny and FluffyChat), and b) have Element go off and build apps which people actually pay for (empirically that means govtech & enterprise).
The hope is that if/when Element is profitable doing the latter, then Element can get back to investing in the broader Matrix ecosystem again. (Separately, it’s fascinating to see how little much of the Matrix ecosystem seems to appreciate the $$M that Element has put in over the years. Funny old world.)
edit: oh, and the unable to decrypt errors should be pretty much gone now; we just spent the last 6 months on crypto doing nothing but killing them.
Uh... I can replicate them right now as I speak, I use fluffy chat on my one phone, fluffy on another android, schildichat and cinny on Linux.
I am logged out of my schildichat every few days, cinny breaks a bit, and sometimes messages just show "could not decrypt message".
They "eventually" show on all sessions but I am facing them now.
My old sessions are broken, only new messages are visible across new sessions.
I use matrix as my daily driver so i it doesn't bother me much but I can say an average user might not.
Also,
Fluffychat android doesn't work with audio calls. Notifications are broken, I get "some" notifications, some days, sometimes after a few weeks, sometimes none.
