register timeout 408 after connection expired

Question

I have installed the Zoiper in my iPhone (iOS) and configured it work OK.

However, after the connection was expired, if I open the app again, the register always fails (timeout 408 error).

I have to switch off / on Wifi and it can register again.

So, each time I open the app, I must switch off / on Wifi.

Any idea to solve this? Thanks.

Hi,

Please be sure that Zoiper stays active on the background.

Maybe this guide will help you : https://www.imore.com/how-to-manage-background-app-refresh-iphone-ipad

Please be sure the app can refresh in the background.
