Help testing upcoming 2.47+ with multi-relay and improved experimental calls

After each call, the smartphone has to reboot, not a sound is played, the video does not play, the ringtones are turned off dullly.

Hello! Calls work fine both on desktop and mobile, but I want to know how STUN/TURN discovery logic works. I want to use my own regular mail server with deltachat, and I have coturn already deployed; meanwhile I don’t want to deploy chatmail separately just for the turn feature.

While reading this thread, I found that if one contact uses chatmail server, then its STUN/TURN will be used for call; otherwise, if both correspondents use regular mail, deltachat will fall back to public STUN/TURN.

Is there some way I can override that behavior and make Delta Chat discover my own STUN/TURN relay for a regular mail server I control? Can I just create stub discovery JSON or http endpoint which will return needed values?
Thank you!

I just tested today with latest release (not the release candidates but I didn’t know where to put this feedback) from a Google Pixel Fold to an iPhone and neither of us could hear audio.

On 2.48.0

Android Murena e/OS. When I receive a voice or video call, when pressing ANSWER the call drops.

Android stock. when receiving calls, screen is black despite ringing, with no way to answer the call.

Both those happen on first call. I guess this happens with app running in background cos on the second call, everything runs as it should. Top quality for both voice and video calls.

yeah! there is new version to test, closing this topic
