Requires phone reboot every few days. After a couple days the app was I'll show that it's unable to register the SIP. The only way to resolve is to perform a reboot of the android phone and then it is fine. I have to do this every 2 or 3 days. They need to fix this by providing at least some kind of forced reset within the app.

The app works well for me 90% of the time. My only feature request/improvement would be that it be more aggressive in attempting to re-register/re-connect after network changes. Many times the app is stuck at the "Registering..." status. If I exit the app and say no to "Do I want to continue receiving calls?" then re-open the app it'll re-register immediately.
