Is there a SIP client for Android that can handle switching between wifi and 4G consistently? It doesn't need to maintain an active call while switching networks. It just needs to reconnect reliably after the phone changes networks.
I've tried Bria, CSipSimple, and Zoiper, but they each have problems after switching networks a few times. In some cases the client says it's connected but it's not. In other cases the client freezes up while re-registering. When either of these happen, I have to close the app and relaunch it to get reconnected. I'd like to find a VOIP app that can run continuously and reconnect reliably.
Is there something I can change in Android or in one of these apps that would make them more reliable?
