I loved this app, easy integration with Android dialer. Was working perfect on my Blackberrz KeyOne but now with the KeyTwo when a call is in or out the app crashed when making or answering a call. But in the notification bar it says call is going on. What to do now, I loved the version on my KeyOne and want to use it on KeyTwo. Could it be that it crash because I have a dual sim phone? if working 6 from the 5 stars!

I've been using the app for almost 8 years now and it's always a hit and miss. For a more stable connection I got a yearly subscription and the very next day it stopped working almost entirely, with some intermittent connectivity surges. Support is being unresponsive for at least 3 days now. For something reliable consider choosing a different VoiP app.

Did not work on my Chromebook :o( I made a test call, I could hear but the call window was full screen, I tried to minimize it and it got lost, it was not in the open windows list, so I had, for the first time in my Chromebook, to log out in order to close something. After a few hours I found out that the call remained open for 3 hours until my sip provider's balance went to cero. I unistalled it since I am quite comfortable using sip only on my Android phone. Thanks
