Am I correct that with the Android phones, you will have to disconnect and call again if you walk from inside to outside and the the UMA phones, you can walk out and you may or may not need to dial again?

My experience with the latter is a littler different than GoingAway's. I don't lose the calls typically when making the transition at home, but I don't have H@H. But, I don't usually look at when the switch is made. Have others found that the transition works or doesn't?
