Skate to Hold/Disconnect

Skate to Hold/Disconnect

I have been looking thru the provisioning documentation but don’t see this feature or a way to change the way the telephone handles an active call when pressing another line key.
Currently the telephone automatically place the active call on Hold (Skate to Hold) when pressing another line key.
We would like to change the behavior to Disconnect the active call (Skate to Disconnect) when pressing another line key.
Working with the T2x and T4x telephones

Thanks
