This application has been deleted and removed from the Google Play Store. However, I have checked their website and they have released a new application called Mobile Monitor. The app has the capability of access call logs and deleted call logs. You just need to log-in on the app using the client provided to you and then the software will be available for usage. For more information, I recommend checking the official website of the application: http://mobi2mon.com/
Call Recordings was a feature that allowed you to listen to the available calls. Unfortunately, I don't see that option available anymore.
