When a FaceTime call comes in, do any of the following:
Accept the call: To answer a video call, tap announce incoming calls, which you can accept or decline using your voice.
If you miss an incoming video call from a known contact and the caller leaves a video message, you receive a notification about the video message, which you can tap to view. You can also find a link to the video in your call history, below the missed call.
Note: You can receive video messages only from saved contacts, people you’ve called, and people suggested by Siri.
After the caller leaves a video message, a link to it appears in your FaceTime call history, just below their call.
If you miss an incoming audio call, the caller can leave a voicemail if you have Live Voicemail turned on in Settings .
