Receive FaceTime calls on iPhone
Answer a FaceTime call
When a FaceTime call comes in, do any of the following:
Take the call: Drag the slider or tap Accept.
Decline the call: Tap Decline or
.
Set a reminder to call back: Tap Remind Me.
Send a text message to the caller: Tap Message.
If you’re on another call when a FaceTime video call comes in, instead of Accept, you see the End & Accept option, which terminates the previous call and connects you to the incoming call.
Tip: You can have Siri announce incoming calls, which you can accept or decline using your voice.
Listen to a video message or Live Voicemail
If you miss an incoming video call and the caller leaves a video message, you receive a notification about the video message, which you can tap to view. You can receive video messages only from saved contacts, people you’ve called, and people suggested by Siri.
If you miss an incoming audio call, and you have Live Voicemail turned on in Settings > Phone, the caller is prompted to leave a voicemail. You can see a real-time transcription of the voicemail and pick up the call as they’re leaving the message. See Turn on Live Voicemail.
After the caller leaves a video message or voicemail, a link to it appears in your FaceTime call history, just below their call.

Note: Live Voicemail is available only in English in the U.S. (excluding Puerto Rico) and Canada.
