I want to have a FaceTime conference call in audio mode, not video mode. How do I invite Android users into audio mode?

Hello ctu102,

Thanks for that info and for choosing the Apple Support Communities. If we understand correctly, you are wanting to have an audio only FaceTime calls with Android devices. Looking at these Apple resources, this isn't possible when creating the link, but once on the call they can turn off their camera to make it audio only, and here is more info:

Use FaceTime with your iPhone, iPad, or iPod touch

Join a FaceTime call from an Android or Windows device

Cheers!
