I don't specifically know anything about this implementation, but T-Mobile had the T-Mobile @ Home program, which allowed you to place cellular calls over WiFi without using minutes.
In that scenario, I was able to start a call on my WiFi and leave the house which seamlessly transferred over to cellular. Aside from the obvious, it's not _really_ much different than a cell tower handoff, and most people don't even realize that's happening all the time as you drive around.
- andrewpi 15y agoT-Mobile now calls that service 'Wi-Fi Calling', and provides it on certain Android phones via software by Kineto Wireless. However, unlike the original UMA solution that T-Mobile BlackBerrys had, the Android software does not support handoffs between Wi-Fi and cellular, and it will drop your call.
