Well now, this proves where, once again, this unfortunate combined Spreed/Talk category is a major mess. It really would make things much easier for everybody if the devs could finally extricate the two from each other. This mangled mix, sometimes containing conflicting instructions, sows utter confusion.
At GitHub - nextcloud/spreed: 🗨️ Nextcloud Talk – chat, video & audio calls for Nextcloud, we read:
Nextcloud Talk is really easy to install. You just need to enable the app from the Nextcloud App Store and everything will work out of the box
It continues with:
There are some scenarios (users behind strict firewalls / symmetric NATs) where a TURN server is needed.
I’m reasonably certain that neither of these scenarios are applicable to my installation.
Or, am I completely missing the boat here? Are those people who experience the full “Talk” functionality really only able to do so because they’ve installed a separate TURN server?
