What happens if I call a landline number using facetime audio?

Can't facetime a landline, audio should go through.

I don't believe that any FaceTime call will go through to a landline number. I don't have a landline number I can call to test but, it's possible the iPhone will recognize that you're calling a regular number and switch to standard cellular service.

What happens when you try?
