I setup the 3CX mobile app on a cell phone to test with an extension. It worked and then I decided to remove the app from the mobile phone. I would have expected the extension status to show unregistered at that point, but it still shows as registered. How do I get the extension in the status area to show the correct state? I could delete the extension and that would probably clear it, but don't think that's the correct method. Extension 74 is the extension below. Any ideas?
