Phone X stuck on FaceTime call ending

Same issue just happened with my son’s Xr. Phone locked up during a FaceTime call and continued to ring. No buttons or apps would work or respond....just constant FaceTime ringing (very annoying). We used the the quick up vol button/down volume then right button trick to power it down as this thread suggested as our solution

I was stuck like you were and did exactly what you suggested and it worked for me too. Very strange. Volume up, then volume down, then power and it gave me the option to shut down.

Hold down power and press the up volume for a couple of seconds then down volume a couple of seconds, then up volume. If you do that sequence, it will restart even if it seems locked up.

Not knowing what version of iPhone that you have, and you seem to have some issues with the newer way to reset your phone, see if this explanation helps.

If your screen is black or frozen, you might need to force restart your device. A force restart won't erase the content on your device. You can force restart your device even if the screen is black or the buttons aren't responding. Follow these steps:

• iPad models with Face ID: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Press and hold the Top button until the device restarts.
• iPhone 8 or later: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Press and hold the Side button until you see the Apple logo.
• iPhone 7, iPhone 7 Plus, and iPod touch (7th generation): Press and hold both the Side (or Top) button and the Volume Down button for at least 10 seconds, until you see the Apple logo. 
• iPad with Home button, iPhone 6s or earlier, and iPod touch (6th generation) or earlier: Press and hold both the Side (or Top) button and the Home button for at least 10 seconds, until you see the Apple logo.

You have to let your phone die

I have this very same issue - it tells me one cal is ending and another one was declined. I cannot reboot my iphoneX in the regular way (i.e. holding volume up and right side button at the same time) - it takes me to phone app, which won't quit. I can start Settings app, but I cannot scroll all the way down in the settings, so i the setting you are referring to is beyond reach. In fact, I cannot open any setting in the Settings app, it seems like it is frozen too. I can force quit and reopen the Settings app all in vain with same exact result. Please advise.

This happened to me when I was in a secluded area, with no navigation and no call allowed, this is a really serious issue. This happened to me on iphone X and also in iphone XS. @apple please solve this.

Its just not up to the apple quality ! This is annoying, irritating and really a hard stop.
