How do you do FaceTime if it says you are busy?

If FaceTime indicates you are busy, it typically means you are on another call or have enabled "Do Not Disturb." To resolve this, you can end the current call or disable "Do Not Disturb" in your device's settings. If you're still unable to receive calls, ensure that FaceTime is enabled in your settings and that you have a stable internet connection. Additionally, restarting your device may help clear any temporary glitches.
