I confirmed this behaviour with a 3CX support ticket and they suggested posting a feature request here... When PUSH is configured for Android smartphones, after the first time a smartphone registers successfully the extension will always as show as registered. The current behaviour of the Android app (14.0.57) is: choose "Exit" in the app, still show as a registered extension and still receive push calls. choose "Exit - Ignores PUSH" in the app, still show as a registered extension and not receive any push calls. Surely "Exit - Ignores PUSH" should also unregister the extension? For desktop phones and softphones the registered/unregistered status is handled correctly, can this please be fixed for Android?
