Display after picking up Handset Receiver - T48S

[cwatts@deltamodtech.com]

Does anyone know where the setting is to change what display screen shows after picking up the handset receiver? I want the DSSKeys to remain displayed on the side of the screen after picking up the receiver. Now when I pick it up it goes to the dial-pad. I know we can push the home or back icon, but prefer it to to stay on the main screen. I want to change the setting via web, not through the physical phone. Thank you in advance.
