I bought this app as I saw a lot of recomendations. But after installing I was completely disappointed. First, because the app is not able to show the video in the right ratio. Instead it streches somhow to fill the whole screen while even loosing a part of the margins. Second, whenever I leave the app, it does not gets noted when its beeing called. I can see in my Asterisk Voip Sever log, that as soon I press the home button to get out of the app, the contact is beeing unregistered and deleted.

worked very well for a while, but now the push notifications server stopped responding to OPTIONS keepalive from my Asterisk and the app no longer works in the background, only in battery-hungry 'standard' mode. Can't find Acrobits support contact...

excellent app stability, user experience, features for both novice as well as pro users. very simple setup for all major SIP voip service providers. Compared to other sip clients that I have used so far, it is by far the best. Highly recommended!
