Sharing Sounds with FaceTime Audio
A handy but underappreciated feature, FaceTime Audio lets you make audio-only calls to other iOS or Mac users anywhere you can get a Wi-Fi or cellular data connection (see Figure 7). If you have a phone plan with a limited number of minutes, using FaceTime Audio is a good way to avoid using up your minutes.
Figure 7 FaceTime can also make audio-only calls that don’t use up your phone plan’s minutes.
You can make FaceTime Audio calls from the FaceTime app on iOS or OS X. As with FaceTime video, just search for a contact by name, phone number, or address, and click or tap the phone icon that appears next to the person’s name. You can also start a call from Contacts by clicking or tapping on the phone icon that appears next to the FaceTime entry in the person’s contact record. Once you’ve initiated the call, you can carry on a conversation just as though it were a normal phone call, hanging up when you’re done.
