642-071 Cisco Unity Design and Networking Training Course

Demo Question 7.

You meet with a customer, EliteCertify.com, who is currently collapsing their IBM/Lotus Notes environment from a multi-site distributed layout to a single data center in Indianapolis. With offices across the United States, (35 of them), and a distributed mix of Legacy non-networked PBXs, you have a very complex environment to try and converge? EliteCertify.com also maintains a wholly distributed Legacy voice mail environment, but wants to treat the data center as a completely new installation with no existing infrastructure with regard to voice mail, and as such is very flexible with voice mail migration options. When you explain some of the potential technical options given their existing environment, they agree that a Cisco CallManager/Cisco Unity solution is optimal. They have a limited budget this fiscal year, and need to slowly move from this distributed PBX/Electronic Messaging layout to a Cisco solution over the next two years. What do you recommend to the customer?

A. You offer them centralized Unity for Exchange as a voice mail replacement, since their Notes infrastructure is distributed. Since Unity for Domino CANNOT fit in this environment for a number of reasons, this is their only option.
B. You cannot help them today, since moving slowly will not work given the need to perform zip and replace? Of PBXs at each of the remote sites. Unity simply cannot fit into their current environment. If they had the budget to perform zip and replace? Then you could help them.
C. You offer them distributed Unity servers on the edge, since Unity MUST reside as physically close as possible to the Legacy PBXs. You put the CallManager rollout on hold as well, until the customer has the funds necessary to support a zip and replace? Strategy for the Legacy PBXs. Distributed Unity servers will also be able to better support the migration strategy you know they need for their centralized voice mail servers. In your next meeting, you MUST discuss the voice mail replacement/migration strategy with the customer.
D. Since they are very flexible with the pathway you lead them to, you offer an initial centralized Unity server layout. Since they will be collapsing at least some of their PBXs to a CallManager layout, and they will be fully centralizing their Notes Messaging infrastructure, you have the initial Cisco Unity servers in the data center service those users who will be on the first round? of migration from the legacy PBXs to the centralized CallManagers. Over time you will add Unity servers as needed to support the customer's timelines and budget. Cisco Unity can even support a dual PBX? integration in the data center, if needed.
