    I have AT&T and recently enabled wifi calling in my area. Whenever I am on a call using wifi calling, I lose the audio when I leave my house and the call goes into limbo when I go back to cellular coverage (call is still connected but no more audio either way). Does transitioning between wifi and cellular work for anyone seamlessly on AT&T?

    If you live in an area with HD Voice and you have that enabled it should hand the call off. I've also noticed a 1-2 second delay when it switches but after the switch the audio returns.

    I have LTE in my area but no HD voice yet. Guess that means it won't handoff smoothly?
