Great app, but the latest update has removed the stop option You need exit for all kinds of reasons, such as when I want to use one of the SIP accounts on another device, or to save battery. Now we have to go through the phone settings menu just to stop the application. BRING BACK THE EXIT COMMAND.
Not up to date While the featureset is nice, the app suffers from a lot of freezes while changing settings. Every time you change a setting it disconnects and reconnects to your server instead of waiting for you to save. It's quite ugly. It's a phone app and the first screen you see looks nothing like a dialer.
Not recognizes my Google Voice account. It not that I dislike it, I just cannot get it to recognize my Google Voice account. It only sees my Google account that I have registered with Play Store. I need help to adjust that.
Echo cancellation needed Everyone I call gets a terrible echo of whatever they say, about 1-3 seconds later. Otherwise, nice app
Not compatible with lollipop Incoming calls not shown as lollipop notifications thus 100% missed.
