OK- cant really help much, as I only deal in Nortel voice mail (nothing beats full integration.)
I can tell you that there is no special programming in the Nortel MICS that is designed to let the switch know that particular ports are designated for voice mail.
So, all of your programming for the Nortel and the Amanda will be in the Amanda manual. I know that most modern Amanda’s allow for direct digital Nortel port integration, but I would just confirm that your particular Amanda allows for this, as opposed to needing an ATA or VMI.
Any other answers would probably be found via the Amanda manual, or Amanda tech support if it is offered. There never has been a whole lot of discussion about Amandas on this board, but maybe someone here is familiar with the product. It is a very important detail that you left out of the title and the first post.
