Hi MichaelHuff,
Thanks for the post in Apple Support Communities. I see that an alarm is going off while you're using FaceTime and when you end the alarm, the FaceTime call ends also. Is that correct?
Is this a scheduled alarm in the Clock app, a Bedtime alarm, or a different type?
How are you ending the alarm? Are you finding that the button to stop the alarm is appearing in the same location as the "End Call" button for FaceTime? Or are you ending the alarm using a button on your iPhone? About the buttons and switches on your iPhone, iPad, or iPod touch
Also, which iPhone model and iOS version are you using?
Feel free to reply back with the answers to the above, and the community may be able to assist further.
Take care.
