Can ZoiPer be set up to always record calls even if calling from the native phone and not the actual ZoiPer App? Does it only work if ZoiPer is open in the backgroup and not if all apps are closed from multi-tasking? We have a user that handles very sensitive information and we set his phone up to use ZoiPer but he doesn't always use the app to make and receive calls, so we want to know if all calls get recorded no matter where he dials from or receives calls to his cellphone. We want to make it easy for him.
