If your cell phone is disconnected from Wifi, wouldn't it just place the 911 call via the cellular radio(s)?

  Wifi would be connected. Underlying internet would be dead. So your cell would try to route through the Internet (via the wifi) to no avail. Try it if you have wifi calling enabled. Just pull the plug on the router and see how long it takes your cell to disable wifi calling.

    Emergency calls normally default to cellular, instead of defaulting to WiFi, as it provides more consistent location information. Even if it tries wifi first, it should fallback to cellular within 30 seconds if a call attempt is made.

      It doesn't try both? A big part of wifi calling is to provide service in what otherwise would be a dead zone.

    I use Fi, and it will refuse to call over wifi if the connection is even slightly finicky. If a cell phone tries to place a call over wifi with no internet and then doesn't retry over the cell network I would call that a bug.
