We have a few people that use their extension with the Android 3CX Client, which works fine. However, the Android clients only show up under "Phones" in the management UI after a recent call. This makes it really hard to see which extensions actively use the client. It would be even better if there was a way to display when the client last checked in. It might be hard to do with clients that have PUSH enabled as these generally sleep for a long time. Our management was enquiring if there was much demand for the clients, but even my own extension didn't display the Android client. After calling myself it indeed showed up in the "Phones" listing.
