Create a dial by name directory with Avaya telephone systems?

I have the phone called: Avaya MLX-20L with the Merlin Legend Control Unit Model 511A. I need to make a dial by name directory so when people call from the outside they can be directed to peoples voice mails. I also need to change peoples voicmails and passwords that have left the company. ThanksCreate a dial by name directory with Avaya telephone systems?
I don't believe Merlins can have a 'dial by name' directory within the phone system. That has to be set up in the voice mail system.

Look for an answer over in the tektips forum. that is more techicnical over there.
