We want to SMS our users with a message containing a link that they can click in an iOS device that will automatically go to FaceTime and call that number. We already have a javascript function setup that will send an SMS message to the user through Twilio:
srvTwilioService.sendSMS(phone, message);
What should the content of the message look like so that what the user receives has a clickable html link that contains a phone number so that when the user clicks it they are automatically placed into a FaceTime call to the number, e.g. something of the logical form:
var msg = '<a href="facetime:14085551234">Connect using FaceTime</a>';
Thanks

SMS messages don't include a notion of markup, so you can't use the anchor tag like you've shown, but I did try just including the text facetime://15555555555
and the Messages app did recognize that text as a link and tapping did deep link me into the facetime app.
Hope that helps
