******* DO NO PURCHASE THIS APP ******* As soon as I open this app I cannot receive calls via cell and they are sent immediately to VM, even after exiting and force closing Groundwire. I must reboot my device to receive cell calls again! (Galaxy Note 8) Please fix this as Groundwire is useless in it's current state! Update: devs are unresponsive. I've uninstalled and moved on to a mire reliable SIP app.
