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.

the app freezes and throws out an 408 error and never loggs in ..set up looks exactly like what I wanted

Works great over wifi, connection is stable. So far the most reliable softphone I have tried. Not a single issue while on a call. Two small issues/improvements: * for some reasons, sign-in over 4g doesn't work. It times out after a while (while it works with other softphones). * impossible to exit the app if interested only in outgoing calls. This unnecessarily drains the battery. I have to 'force close' the app after using, which is a bit of a pain.
