iOS 15.4 dropping calls

After updating to iOS 15.4 on iPhone 12 when trying to answer a call it drops the line.

The screen sometimes becomes non responsive.

Before updating I also had “call failed” quite often.

If you wish to troubleshoot the phone more, you can create a backup of the phone, How to back up your iPhone, iPad, and iPod touch - Apple Support and then restore to that backup Restore your iPhone, iPad, or iPod touch from a backup - Apple Support and test.
