Hi, I am having a strange issue which I cant figure out why its happening and how to resolve it. Hope you can help. 
For some reason I am able to make and pick up calls on my iphone over 4G using the Talk app. But when I try to make or pick up the same calls using a web browser from within my local network, that also hosts the nextcloud infrastructure, it will not connect, only spins around on the caller name as if its loading. I can send messages and use the rest of nextcloud fine. Any ideas what is happening?
I have a separate TURN server installed on our network and configured a high performance backend on the nextcloud server, and both are working fine according to the config/status pages.
Nextcloud version: Nextcloud Hub 7 - 28.0.4
Operating system and version: Ubuntu 22.04.2 LTS
PHP version (eg, 8.3): PHP 8.1.2-1ubuntu2.18 (cli)
On two separate VM’s NginX and a TURN server are installed
nginx version: nginx/1.18.0 (Ubuntu)
It looks like there are no errors that would indicate the issue:
Hope someone knows what the issue is and how to resolve it. Thanks and enjoy your weekend.
