Ratings and reviews

What I like about this app is how it integrates with my contacts. The app gives me the option to dial a contact either from my cell phone or through my VoIP via the app - very cool! However, I have to subtract 3 stars because on the latest version which I installed there is no keypad, and all the other tabs for call Log, contacts, and groups are also missing. 3rd UPDATE: just tried reinstalling the app again but the same problems remain. Had to return back to ZoiPer.

Overall I find this a reasonably good app. A little difficult to setup and, for me, it won't work when I'm using my VPN. The only downside is since the last update I can't use my ear piece as it doesn't work anymore. The earpiece is good as I have checked it using the phone SIM. Hopefully this will be fixed on the next update. Definitely worth a try.
