Dan231,
The old fashion way(s).
1. Go to the phone and use the Program Key Feature Code (Default=397), Press the key you want to program and dial in the digits you want.
2. Database Programming: System > Devices and Feature Codes > Phones > {Extension to Program} > Programmable Keys
You would also have to know which programmable keys are assigned to their keymap and where they are on the phone.
System > Phone-Related Information > Key Assignments > Keyset > # {keymap associated with phone}
or
System > Devices and Feature Codes > Phones > {Extention to Program} > Keymap > Double-Click on the Keymap #.
Look for any keys that are programmed User-Programmable Key #. The # is the key number you would program under their phone Programmable keys.
Personally, if there are a lot of them it is easier to just have the program them via the Feature Code 397.
Thanks,
TE
