Under LD 18 build your speed call lists. You can build 100 at a time. Then for each phone in the system that you want to, assign a Speed call number and make them a speed call controller. On the multiline set do a chg then for
key x scc xxxx
let the individual users build their own speed call lists,
we usually give most folks 10 numbers 0 thru 9
certian folks might need a system speed call and we give it 100 places to fill. If you have a features guide read up in there, everything else is ld 18 then ld 10/11 or use ld 20. If using MAT or OTM you can do a global update which is quicker.
