# Fix 3CX Extension Not Registered Status

## Problem
A 3CX extension showed as not registered in the system, preventing proper phone functionality. The user could dial out but their extension appeared unregistered in the 3CX interface. The issue was occurring while using the web app version of the 3CX client.

## Resolution
1. Clear browser cache and re-login to the 3CX web app
2. If cache clearing doesn't resolve the issue, download and install the latest 3CX app from the Windows Store instead of using the web app
3. Test incoming calls to verify the extension is properly registered - in this case, a colleague was able to successfully call the extension, confirming registration was working despite the display issue

The registration issue resolved itself after these troubleshooting steps, with incoming calls functioning normally.
