CUDN v1.1—1-14 Deployment Strategies for Migrating from Voice Mail to Unified Messaging Two strategies –Strategy 1 All new equipment; the only shared equipment is the phone system and the way the alias is built Separate forest New mailstores –Strategy 2 Same forest (modify schema) Use existing equipment for mailstores Alias must be unique form existing

15. © 2006 Cisco Systems, Inc. All rights reserved. CUDN v1.1—1-15 Summary There are three Cisco Unity configurations—Single-Server Voice Messaging, Multiserver Voice Messaging, and Unified Messaging. Cisco Unity deployment models can be either centralized or distributed. Cisco Unity deployment models are combined with the IP telephony deployment model for a total solution. Dialing domains are used with cross box logon or allow auto attendant transfers between Cisco Unity servers. Digital networking is the how Cisco Unity transfers messages between subscribers on different Cisco Unity servers. There are two deployment strategies to consider when deploying a voice mail to future unified messaging configuration.
