I have a CICS 8/16 with Flash VM 4. I want to free up a couple of buttons on M7324 phones (right set of 12 buttons) so can reprogram with flash functions 981 and 986. The right set of 12 buttons are all programmed by default (which I have never changed). Just doing a Feature *3 will not work (won't accept the feature code), so I am assuming this means I have to change the default programming, but haven't found the section in the manuals where this tells me how.
