In all my recent FaceTime tinkering it came to me that I could easily post my Google Voice phone number as my FaceTime number.
The idea being you could post the Google Voice number anywhere. You can accept or decline audio phone calls however you see fit and convert any audio phone call you want to make a FaceTime video call seamlessly with the press of a button.
Many popular tech people on Twitter publish their phone number. Having that number be a Google Voice phone number would allow you to have multiple phones and allow ‘protected’ FaceTime calling since they’ always start as audio calls, you can also have call forwarding and other controls.
Another great thing about Google Voice.
