Apple iOS:
To be reachable with Zoiper for longer than 15 minutes please adjust some settings for your iOS device.
The following settings should enable you to register for up to two hours without app interaction:

Settings -> Incoming Calls:
Force background: change inactive to active
Wi-Fi Keep Alive: change inactive to active

Windows Phone:
With Windows 8 it's not possible to run applications like Zoiper in the background.
Currently, it will only be possible to receive calls on a Windows Phone when the application is in the foreground. This is a limitation imposed by Microsoft on their operating system, not present with Android, Apple or Blackberry devices.
If you're encountering audio issues with Zoiper on Android phones, a change of audio drivers can help. Please open Zoiper and find the option under Config -> Audio -> Audio driver. Please select "External Java Driver" and exit Zoiper. After a restart of your device the new setting should apply.
Error 400 Bad Request:
If you're encountering issues with Zoiper registration and receive the error message 400 Bad Request, please check if Push Notifications are enabled in Zoiper settings. Push Notifications are not supported with sipgate services.
