Most FaceTime calls start when one iPhone owner directly calls another. But the FaceTime apps on iPhone, iPad, and Mac offer another way to make calls too: by creating a link.
How to create a FaceTime link
A FaceTime link lets anyone join a call, even if you don't know their phone number. This makes it great if you want to chat with someone whose number you don't have, or if you just want a call to be open to a lot of people. This is also how you can FaceTime people with Android or Windows devices.
To create a link, open the FaceTime app on your iPhone, iPad, or Mac. Then click Create Link in the top-left corner.
A menu will appear that lets you quickly share the link with contacts or through an app. Pick one of these options, or select Copy if you just want to save the link to your clipboard. If you do this, you'll need to paste the link somewhere to save and share it.
While you're in your call, you can also grab a link by tapping the options toolbar and then selecting Share Link.
When someone clicks the link, they'll need to tap the Join button at the top or bottom of the screen. They might also need to give permission for the app to use their camera and microphone.
And once they tap Join, the person who made the link will get a notification to let them into the call. Either tap the checkmark icon on the notification, or tap the options toolbar inside the call and let them in from there.
Once everyone leaves the call, the link will expire and the meeting will end. You'll need to make a new link if you want to do it again.
