Signal video/voice calls over WiFi latency

For quite some time I’m struggling with Signal calls when using WiFi. It works fine when using 5G. So you might think, it’s your WiFi at home. But when I do the Signal call on my laptop, the latency of about 1-2 seconds is gone.

So if it’s not the network, it may be the device. Do others also experience issues when calling someone over WiFi on your Fairphone 5?

Some speed/latency tests:

I had no issue with voice calls using my WiFi, does this happen to you specifically with video calls? (I personally don’t think video is necessary for a call so I just don’t have videocalls with others)

It happens to both video and voice. You experience no noticeable latency? There is a huge difference between calling with my phone or with my laptop. I don’t have this issue with Whatsapp or Teams. The combination of Signal, WiFi and Fairphone seems to be it for me.

It seems that the FP5 is hit bad by buffer bloat. I experience this also
