Rafa0612 , via OnePlus 7 Pro , Jul 29, 2021 : My VoWifi call goes in a state where I'm not able to hear anything amd then it disconnects when my wifi switches to a different router in the mesh network. I have setup 2 routers in a local mesh network at my home for better connectivity, so that the devices can switch to the one with the strongest signal. But when that happens my VoWifi call gets dropped. I tried the same thing on my friend's iPhone but it was working perfectly. Seems like an issue with OnePlus's implementation. If anybody knows how to fix this issue do let me know.
