You give the extension permission to use RCF through WinSPM. To remove that permission, go to the same screen, dial the extension number, and press Delete instead of Enter.

But if you want to cancel the extension from forwarding to an outside number, it's just #33 and that phone's own extension number (forward to itself to cancel any forward)
