Additional Information
Troubleshooting FaceTime calls
If you're unable to activate or make FaceTime calls, try turning FaceTime off and on again using the following:
iPhone: Settings > Phone
iPad 2 and iPod touch (4th generation): Settings > FaceTime
FaceTime for Mac: FaceTime > Preferences
If you can't place a FaceTime call to a particular contact, try the following:
Verify that you have the correct phone number or email address.
Use the correct method of contacting the person. If you are calling:
An iPhone 4 user: Use the phone number
An iPad 2, iPod touch, or FaceTime for Mac user: Use the email address
Check that each person has an active Wi-Fi connection.If you are using router, firewall, or security software that restricts Internet access, verify that port forwarding is enabled.
Verify that the date and time are set correctly on your iOS device or Mac.
The Apple ID you are using to register FaceTime on iPad 2, iPod touch, or FaceTime for Mac must be an email address.If your Apple ID is not an email address, you can change it on appleid.apple.com. This article provides instructions on how to change the Apple ID.
When calling someone using their email address, they must verify that email address for use with FaceTime and be signed in to their Apple ID account. They can verify they are signed in using:
iPad 2 and iPod touch (4th generation): Settings > FaceTime
FaceTime for Mac: FaceTime > Preferences
Note: If verification is pending, follow the instructions in the email that was sent to that email address to complete verification.
