SCCP extensions tab disappears from FreePBX Extensions module

[jpanzer1]

After a certain period of time, notably after doing module updates, the SCCP extensions tab seems to disappear from the main FreePBX extensions page. Seems as though after module updates, the hook is being removed from the Extensions page.

As a result, you can no longer add SCCP extensions. If you do so, you get an error when you attempt an add due to a "null value". Existing extensions still function normally.

The only way I've found to fix this is to uninstall the module and reinstall the module. Unfortunately this also wipes out the SCCP device database and puts a new blank one in place, disconnecting all SCCP extensions.
