You can send a FaceTime voicemail to someone if they don’t answer your request for a video chat. It’s better than leaving a regular voicemail because it’s video — you can relay a message quickly or show something off on camera.
For instance, if your dog or your human child is doing something cute, or if you want to get a second opinion on an outfit, you might want to show someone. If they don’t answer your FaceTime call, you can record a video to send them to watch later.
