Random error I’m getting is with recording the audios. Some of them do fine, some can’t be played by both parties. It shows as zero length voice message. I didn’t have such behavior on previous versions. I believe this started around 2.46-47, but I might be wrong. I managed to record this behavior: Also I have two imported relays, they are active on pc and phone two. On PC I often get two simultaneous sent messages, one which is read and one not, doesn’t matter if it’s text or audio: ![image_2026-04-18_13-27-16](https://support.delta.chat/uploads/default/original/2X/6/683aa95ef97ba2d63af7789cb010b5472750206e.png) ---

Phone/Video calls initially worked - although when connected to a VPN it would freeze every few seconds briefly. Turning the VPN off fixed this. However, after adding extra relays, the calls are now not connecting, as soon as the person answers the call, it fails. Both ends of this issue were tested on Fairphones, running e/os on Delta Chat 2.49.0 downloaded through FDroid. Could this be due to relay servers not correctly configuring the “TURN” server? ---

> [@recall](#): > > VPN it would freeze every few seconds briefly. Turning the VPN off fixed this. Sounds like a problem with the VPN being slowish. > [@recall](#): > > as soon as the person answers the call, it fails How exactly does this happen? They press the button and then immediately the call ends (and goes to the “main screen” on both ends? Also do you mind sharing the list of relays, possibly privately? ---

Sure, I can DM you the relays on delta chat.

OK, the problem likely was that indeed one of the relays’ TURN server is not functional, and that was the one used for the call. I suspect though that what we actually want is to [Calls: use all relays' TURN servers, not just one](https://support.delta.chat/t/calls-use-all-relays-turn-servers-not-just-one/5374).
