What is causing random end-of-call sounds on my iPhone 17?

There is no iPhone 17, 15 is the latest model.

Try a forced restart.

• Press and quickly release the volume up button

• Press and quickly release the volume down button

• Press and hold the side button.

• When the Apple logo appears, release the button.
