How do I remove having to press dial on digium phones?

All, we have a setup using latest AsteriskNOW, FreePBX and Digium phones with TDM card for analog lines. I have been trying to figure out how to remove the option of having to press dial softkey in order for the call to go through. Does anyone know how I remove this option so that the user can just pick up the handset, dial their number and the call goes through without having to press the dial softkey first?

See freepbx.org/forums/ as to if and how to enable overlap dialing under FreePBX.

Thx for the info!
