iPhone 6 not ringing with os 11.2.6

Hi, garyfromworthington.

It appears that, from time to time, you're not hearing when a phone call is received. You're not provided a ring-tone and the call goes straight to voice mail. I'm happy to help.

Use Do Not Disturb on your iPhone, iPad, and iPod touch -- Make sure that Do Not Disturb hasn't been turned on.

Turn Do Not Disturb on or off

When Do Not Disturb is on, you see a in the status bar. There are two ways to turn Do Not Disturb on or off:

Go to Settings > Do Not Disturb to turn on Do Not Disturb manually or set a schedule.

Open Control Center, then tap .
Take care!

Hi there, I am also having the same problem - phone not ringing at all and no alert that I’ve missed a call. Are you suggesting Do Not Disturb is turned on? I can assure you it’s not on - I’ve never used this feature and have checked several times to make sure it hasn’t somehow turned itself on. I’ve done a hard reset on my phone and reset my network settings. The issue has persisted.

I have this problem also and my phone is not on do not disturb... are there any other potential fixes?
