To diagnose the problem:
1. Put the IPAD in a profile with parental control disabled first. Are you able to use FaceTime and Messaging?
—Yes Facetime works fine.
2. Turn on parental control for the profile. Turn off “block literal IP…”, “Block proxy…”, etc. Choose System Default for DNS. Are you able to use FaceTime and Messaging?
—-Facetime works, but is choppy, audio may work or not, the video may freeze.
3. Change DNS to OpenDNS and test again.
—-Its on OPENDNS, no change, still works like step #2
