With the following you will be able to register for up to two hours:

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.
