Do you pass the firewall checker on the PBX? Also who is your provider? From your description your issue may be due to the fact that the call is not being disconnected. In this case you will need to set the PBX to verbose mode. Go to Dashboard / Activity log / Settings ans set the logging level to verbose. Restart all services. Then try the call back again and check the activity log for the reason the callback failed.
This is the log:
