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.

Not sure why some knock this app. It's clean, simple, lightweight and reliable. Works well with both my upstream provider and my own home grown solution. Even offers features usually only found with "premium" VoIP clients. Even run this on older, low ended Android with limited memory as it's not bloated. Thanks dev! Stay safe and keep up the great work!

Rule-based approach to selecting carrier is cryptic. It will route any call you make through a voip, even if my regular phone would serve better. CSipSimple, which can't be installed any more, gave you interactively the choice of carrier at the time of a call. There is no better way.
