Of course an update comes out the day I delete the app. After the reinstall and setup, one call dropped @ 17s, the second dropped @ 13s, two more wouldn't even connect. I also tried the airplane mode workaround, no connections. Redeleted.
Yep. In addition to having a terrible user interface, it just plain doesn't work reliably, and there doesn't seem to be any way to make it work reliably. For me, It's back to using the network extender for calls at home. The network extender isn't reliable either, but at least it mostly fails when attempting to make calls, and not in the middle of them.
