I used the official documentation

HowTo: Setup Nextcloud Talk with TURN server

Background The configuration of Nextcloud Talk mainly depends on your desired usage: As long as it shall be used only within one local network, nothing should be needed at all. Just verify that all browsers support the underlying WebRTC protocol (all famous ones do on current versions) and you should be good to go. Talk tries to establish a direct peer-to-peer (P2P) connection, thus on connections throughout the local network (behind a NAT/router), clients do not only need to know each other…

@mvv_vmd
the documentation you are referring to, is not optimal, it misses out on thing to be explained and it uses configuration parameters and combinations which are outdated or need some more information to get them working.
