Diasble incoming call display on 3911

[mschmidt]

I have a situation here where I need to install a 3911 phone, however the users do not want the

incoming call dispay to be shown.  They still want the display to work to show the time, digits as they dial, etc.  (i thought about opening the phone and snipping the display wires).

Anyone know of any settings in Call Manager (7.1.3) that would allow me to set this?

Thanks

Closest thing I can think of is using a 'calling party transformation css' on the phone setup to change the calling number to something else like a '+' or something.
