Paul,
To see the Extensions Programmed You would need a laptop and SPM ( Print Extensions) You can't do this on the Console.. Programming the Cover Button. Go to the extension,press Menu program Button and choose from the list " Cover Int. the Ext #10, Select a Button)When the Incoming calls Ring the Console.. So will the Covered Extensions Hope this Helps
If You are Over 7 .. It won't work Good Luck
