I am about to lose my mind. I have been fighting this issue for almost a year.
I live in a poorly served area for Verizon Wireless. To compensate, I use VZN Wifi calling. These WiFi calls drop CONSTANTLY.
I have gone to "data only"... I have disabled "Wifi assist"... everything!!!!
I checked my internet connections and speeds/quality.... 200m down, 30m up... 88% quality.
I replaced my modem/router. no change.
I put a ticket into Verizon and they said they would investigate. They did, and "it's Comcast's issue". I spoke with Comcast, they ran tests and they say "it's a Verizon issue".
I cam caught in the middle with countless calls dropping and "Call Failed".
Can anyone assist???

If you're in an area that has both a Wi-Fi network and a weak cellular signal, sometimes your Wi-Fi calls will fail. Looks like it’s a result of the phone trying to connect to the cellular network instead of sticking with Wi-Fi
A solution that has worked for me is to disable the cellular option. It’s a bit clunky but has worked out pretty good so far. Using the iPhone Control Center (accessed by swipping up from the bottom of screen - adjusted in Settings > Control Center):
- Turn on Airplane Mode (to prevent the phone from being able to use cellular)
- Then I turn Wi-Fi back on. Cellular is now Off, Wifi On
I have the same problem on a Galaxy S8. No reception at my house, so I use wifi calling. Wifi calling works fine but will disconnect randomly when I'm talking. Ut will also not stay connected when I'm not using it. I have done a factory reset and still does not work
