To long time connected on LTE mobile data

[alexzh16]

Describe the bug I connected one mobile device to WIFI connection and other device to mobile data or connected both mobile devices to mobile data. Then I make a call and accept from the other side. Signalling is working fine, but streaming is connected too long time (from 5 to 40 seconds). If I connected one simulator device to WIFI MacBook and other iPhone device to mobile data. Then I make a call and accept from the other side. But streaming is connect better from 5 to 25 seconds.

Turn server working fine.

To Reproduce Get two devices. Connect one device with WIFI and the other device with mobile data (4g or 5g). Then make a call from one end and you will see streaming is not happening.

I am not sure that such issues are related exactly to flutter-webrtc because for all ICE stuff, it just uses Google WebRTC library.

Did you try to reproduce your connections cases with the browser bases WebRTC client? It could give the understanding that is the issue in your network environment or with the current Google WebRTC library version used by flutter-webrtc. And as a bonus, browsers have great WebRTC troubleshooting tools that could help troubleshoot.
