iPhone over-riding audio settings when receiving an incoming call

• Restart the device. That's it.
• Still not solved --> Force restart iPhone - Apple Support

Please check you may have enabled --> Settings > Accessibility > Touch > Call Audio Routing > Bluetooth [Ticked]

Please set it to Automatic.

Please see the pic below made on iPhone 12 Pro iOS 16.5. The two scenarios which I tested are given below and are self-explanatory

Wondering if you ever found a solution as I’m experiencing the same problem with a 12ProMax running 16.4 and 16.6. Notifications are off in every location we can find, settings shown in this post were all verified, turned off emergency notifications/lists. Nothing

I just recently figured out what was causing this issue for me. I have beats headphones and I had the same problem where phone calls were not going to my Bluetooth headset. What I discovered was, by habit, I was swiping on my screen to answer the phone. What I need to do to fix this problem is use the Bluetooth headset to answer the phone by pressing the button on the headset it answers the phone and routes the call to the headset. I have the same problem with my car stereo if I swipe on my screen to answer the phone the call goes to the regular phone but if I push the answer button on my car stereo the call is routed through my car stereo
