html - Apple FaceTime URL Scheme not initiating call

Question

Using Apple's URL Scheme Reference for FaceTime Links on a website, the link opens the FaceTime app but doesn't pass the number/email to be called or start the FaceTime call.

<a href="facetime:user@example.com">Connect using FaceTime</a>

Is this scheme still supported? Any thoughts?

Additional Info Edit: This is the actual code I'm using:

<a href="facetime:user@abc.com">Apple FaceTime</a>

This image shows the popup asking if I wish to place a FaceTime call after clicking the link:

This image shows the open FaceTime app where nothing happens.

Answer 1

When you click on facetime URL from a webpage it'll prompt user for permission. Auto call initiation will only work from native apps and won't work from webpages.

From FacetimeLinks Reference

When a user taps a FaceTime link in a webpage, iOS confirms that the user really wants to initiate a FaceTime call before proceeding. When an app opens a URL with the facetime scheme, iOS opens the FaceTime app and initiate the call without prompting the user. When opening FaceTime URLs on OS X, the system always prompts the user before initiating a call.
