When your Wifi UMA signal is too weak, it switches over to EDGE, but a lot of the time this causes a problem and results in a call dropping. I get the same problem. You get free calling when calling using UMA so that is why it prefers that. Also I believe when your phone goes into "SOS" mode, this is when you have too bad of a signal for wifi or EDGE, and the phone goes into an "emergency call only" mode, called SOS. Correct me if I'm wrong on the SOS part though.
