get a cloud server and try them. easiest way to setup:
no: different name and approach.
yes: office suites. handle documents.
why? if you can edit a text with either of them.
collabora: “streams” the app to your browser. “server based”
onlyoffice: the app is running in your browser. “client based”
kind of big vs. thin client.
and they have different compatibility level to MS Office.
google can tell you: → collabora vs onlyoffice
that’s also my understanding of this app.
that’s voodoo. and those how know won’t share their knowledge with infidels. (i’m a bit p***ed because i couldn’t setup a working version on aws right now. and no one in the forum helped me out.)
you need stun/turn. for my understanding.
that won’t be involved in talk/spreed/stun/turn. different ports.
sure. because it’s not https. and not the same ports
the problem is - as far as i know - that two machines behind NAT won’t find each other. and therefore need a stun/turn server direct attached to the internet.
