My phone goes to voicemail 99% of the time, I am missing calls. What can I do to stop my phone from ringing and receiving my calls?

• Check your DND status - Settings > Do Not Disturb; Use Do Not Disturb on your iPhone, iPad, and iPod touch - Apple ...
• Check BedTime Status - Clock App; Use Bedtime to track your sleep on your iPhone - Apple Support
• Check your Sound Volume; Adjust the volume on iPhone - Apple Support
• Check your Ringer switch; If you hear no sound or distorted sound from your iPhone, iPad, or ...

I now have, and have in the past, had the same issue.

At the same time though the volume is set to HIGH it is barely audible, go figure.

Changing DND did not work this time.

Changing focus does not appear to do anything.

Haptics is "transmitting through touch"; oh you hear the ring through your finger. Somethings wrong with my finger.

If you have access to a second phone side by side; and with each setting change, ring your phone until you get it working.

I wonder that "head phone notification" is the issue.

I always put my phone on speaker; with the volume on high all the time. No head phones here.

I think the iphone knows not the difference; between speakers set on high volume; and a head phone set on high volume.

Apparently if you, or I exceed the phones 7 day limit for high volume; the phone gives us a time out; by electronically reducing the volume plus perhaps disabling your access to the phones volume control.

When the phone is not in sleep mode it should ring for all calls first time every time. Period.

If you don't want to hear the phone leave it in the car, or in a quite place.

Never turn the ringer off, I never have, but it always seems to be off.
