This app does not implement background update feature. To receive calls, I have to make sure its running in the background. If I ever to close it, no luck, I am not getting calls from anyone.
This is supposed to be a front end of a phone service. It should always be on and background update is the only way to do this, to name a few: Skype, Fongo and textplus all do this. App closed, still get notification for incoming calls. Just not jabber.
