Q: Do Not Disturb - Disturb Me when phone is locked

DND is turned off.  Within the Settings, at the bottom of DND there is a SILENCE header that has a check next to Only when iPhone is locked.  The only way to uncheck it is to check ALWAYS, which I don't want.

Nope, no crescent moon and when I swipe from the bottom of the screen up, the moon is not highlighted. I verified, DND is not on.  It just started happening a few days ago.

OK, I can't believe that was it, but now the phone call shows up when called and when I take it off mute it rings as it is supposed to.  I'll leave it alone for now, although I may be back if it happens again.  It works, and I give KiltedTim all the credit. Thanks...
