To prevent incoming calls from interrupting Walkout Song DJ, you will need to do the following steps:
- open your iPhone settings app
- tap and open the 'Do Not Disturb' option page
- set the 'Manual' option at the top of the page to ON (moon icon appears on notification bar)
- set the 'Silence' option at the bottom of the page to 'Always' so it will block calls when the phone is locked or unlocked.
- set the 'Allow calls From' option to 'No One' so it does not allow calls from your favorites to get through.
That should do it.
Of course, don't forget to turn the 'Do Not Disturb' option back to on when you are finished with the game so you don't miss calls
