I have a Cisco CP-7841 and trying to create a "forward all" option on the softkeys. I have tried to modify the button items but it won't allow me to save the changes. I have added an attachment to show that it's currently option 21.
You can not save it, because you probably modify the default Standard Softkey Template --> >You can not save this one. You need to make a copy of it and modify the copy.
