With many of the older phones, like the 7900 series, you could delete the ITL file on a phone by unlocking the phone and then hitting the delete softkey. With the new 9900 series of IP phones, including the 9951 and 9971, there is a new method:

  • Settings key
  • Select Administrator Settings
  • Select Reset Settings
  • Choose Security Settings (you can also choose All Settings if you’d like)

That’s it. Press straight forward.
