Call Recorder funktioniert nicht

To record an incoming call, first answer your call, next open our app and tap on the “Record” button, then you can carry on your conversation with recording enabled.  To record an outcoming call, open our app, tap the "Record" button, call our service number first, and then start your own call.  Call Recorder uses the conference call feature to record your conversations. It’s simple.  Account will be charged for renewal within 24-hours prior to the end of the current period, and identify the cost of the renewal.  After the the call ends, you can access the recording, replay it, and send to another app and more.  Subscriptions automatically renew at the end of each term unless auto-renew is turned off at least 24-hours before the end of the current period.  Payment will be charged to iTunes Account at confirmation of purchase.  Auto-renew can be turned off at any time from your iTunes account settings but refunds will not be provided for the unused portion of the term.
