WiFi Calling

I have Tmobile and when I am talking on the phone while connected via Wifi and leave the Wifi area the call automatically drops. It switches from UMA to EDGE but I always get the favored "call failed" sign. Can anyone tell me if there is a way to fix that, it's really annoying.

What OS do you have?

There is a way to fix that. See my UMA setup guide in my sig.
