Convert Teleworker Back to Office Phone? 5530E IP on 3300

[AzJoe]

I setup a phone to be a teleworker and now I need to use it as an office phone.  It won't prompt me to register it even after removing it as a teleworker phone.  Is there a way to force the phone to re-register?  Does anything need to be done in the 3300 system to kick it out?  I did delete it as a MiNet device but that didn't help.  Any help is greatly appreciated.

Unplug the phone, press the up and down arrow keys simultaneously and plug it back in.
Keep the arrow keys pressed in until the menu appears. Go to Tools and Features, Restore defaults, and press Yes a couple of times.

You can hold 7 while booting and it'll take you into the teleworker set up, it should give you the options for new settings & delete current settings.
