I haven't tried moving it to another button. Only trying to remove the button labled DXD.
I agree that only Ext. 10 can have a DXD button. I'm seeing the DXD button by getting into Ext. 21 from Ext. 10, Feature 00, System Program, System Program, Central Tel Program, 21.
I discovered the button when I was testing ext 21. It was suppose to be Line #2. When I went back to Ext 10 I discovered it said DXD not Line #2.
I went into system programming removed it, but it keeps popping back up. I remove it, it shows blank, when I do a #301, 3 Select a button, it won't allow me to assign Line #2 to that button.
I will go directly to Ext 21 and do a Feature 00.
