Removal of Call back option from Attendant console in 4400

[pb_chandrasekhar]

While calling an extension from 4035 Attendant set in 4400, we get an option of callback on the display. By pressing that key instead of Ring key the LED on the user phone starts blinking and it creates confuson once the customer has voice mail feature.

Hence i want remove the Call back option from console.

Is it possible?
