Disable Users from programming buttons on the telephone

[keithyoung2005]

Hi sorry in advance if this has been answered, I couldn't find it

We are having an issue where users are adding "lines" of co-workers to their phones and not "BLFs" from the telephone interface.

They are then annoyed when they get VM alerts -> Screen is telling them they have x messages, when they personally have none, but the "line" user may have messages.

My questions is two-fold:

(1) Is there a way to stop the notifications appearing on the phone, when other lines are programmed to the softkeys as a "Line"

(2) Can I block users from adding button mapping on their phones.
