Answer 1

Hello,

This is due to the way Zoiper tries to prevent the phone from sleeping, so you can receive call on background. We have resolved this with our latest update and the implementation of PUSH notification. However, we are still awaiting for Apple to approve the PUSH in-app purchase. As soon as Apple approves the new in-app purchase, you will be able to try it.
