Ratings and reviews

One of the best softphones I tried sofar Edit 11/11/25: It was that until the last update... they removed the feature that I can be called while having a mobile call. Now it just auto cancels an incoming call, when I am in a call outside the app. Edit: 17/11/25: I also noticed that the call somehow get stuck... even you don't see a call. The alarm isn't working anymore and the voice recorder and so, the phone says it's in a call that happened with the update before and the one that came out now.

This app UI is not even working properly In my Android device now is fully screen mode and my buttons in the bottom side I can't press any menu button also same account working from zoiper not working from this app

App works well, but Android navigation controls overlay the PortSIP controls.
