Does anyone have experience with an Avaya Modular Messaging and Unity integration? It seems like it would work, but I can't find any doucmentation on this effort? I have a customer that has a large Modular Messaging and intuity install base today and wouldl like to migrate to Unity, but the integration of the two voice mails and the ability to share address books and VMs between the two systems, much like Unity Bridge does for Octel.
