When you re-open the app you scan the QR code from inside your account again, this will pick up the latest configuration information.Please make several test calls into your number, and several test calls out, using the app. The app will make some adjustments automatically on the first few calls, and will also ask for permission to use your contacts and microphone. Any audio issues will automatically resolve after you have completed these test calls.
