I use a similar process.

set up DSS button on phones (either first extension or dist hunt grp port)

In the Stratagy
Create mailbox '8'
set direct message box in config as 8
set digits in a mailbox that starts with 8 to 1

transfer by pressing the vm trans button, 8, ext number, hang up

call goes directly to user's box

similar logic but fewer keystrokes to xfer

have fun
