This article will describe how to display your other permitted extensions on your display so that you can see incoming calls and/or answer them. If you haven't been setup with permissions to view the other extension, then it won't be visible, and you'll need to create a new ticket request.


Please refer to the phone layout found here for button names:

  1. Find an open area on the display where you want the extension to show up and press one of the "Line" keys directly beside it.
  2. Click the "Add" soft key.
  3. Click the "Feature" soft key.
  4. Select the option which shows the extension number. Eg T500 would be extension 500.
  5. That's it, press the home "Phone" key to exit.
