I have time blocks setup on my child's Samsung S7 edge phone. We have the emergency contacts enabled through Norton Family Parental Control (NFPC). These are the steps...
1. Open the phone app
2. Scroll to a non-emergency contact
3. Hit the call icon and that's it.
The NFPC blocker popup will come on immediately after hitting the call icon, but the call is still going through. You can swipe down from the status bar and see the call notification; just a regular call during unblocked time. It has all the icons for call going on and ending the call
