Works great but can’t make the phone call work – Berkanan Messenger Review

Yes this a great app and perfect for when you have no coverage. However I cannot get the phone call option to work. When I select another user and click the phone call icon it rings once and hangs up before the person has a chance to answer it. Also even though I have all notifications turned on it only seems to badge the app for a new message instead of displaying as a persistent notification on the screen like iMessage would. I have persistent notifications turned on for Berkanan. Otherwise 5 star.
