Your customer has ten offices across the country with Octel voice messaging systems in each. They need a voice-mail-only solution that will not impact the current Active Directory they are using. As part of your design you need to add a migration path to get them from a Cisco Unity and Octel interoperability solution to use only a Cisco Unity solution. They plan to change one office to Cisco Unity every three months, but they must have the ability to send and receive messages between users in all offices at all times. They use Octel analog networking between the offices now. They want to start with the Nebraska site.
Select two statements that offer the best choice for migrating from Octel to a complete Cisco Unity solution according to the design process. (Choose two.)
A.
Gather the Octel serial numbers, Octel node IDs, telephone numbers, and user extensions for each office.
Install Cisco Unity and a Cisco Unity Bridge in the customer current Active Directory forest, then create a new serial number and dial ID for the Cisco Unity and Unity Bridge primary location information. Create delivery locations on Cisco Unity using the Octel dial IDs and telephone numbers you gathered from each office. Install the users for the Nebraska office. Force name net emulation to replicate the user database. In three months repeat these steps at the next office.
B.
Gather the Octel serial numbers, Octel node IDs, telephone numbers, and user extensions for each office.
Install Cisco Unity and a Cisco Unity Bridge in a new Active Directory forest separate from the customer current forest. Use the Nebraska office Octel serial number and dial ID for the Cisco Unity and Unity Bridge primary location information. Create delivery locations on Cisco Unity using the Octel dial IDs and telephone numbers you gathered from each office. Install the users for the Nebraska office. Force synchronization through the Bridge server to replicate the user database. In three months repeat these steps at the next office.
C.
Gather the Octel serial numbers, Octel node IDs, telephone numbers, and user extensions for each office.
Install Cisco Unity and a Cisco Unity Bridge in the customer current Active Directory forest, then use the Nebraska office Octel serial number and dial ID for the Cisco Unity and Unity Bridge primary location information. Create delivery locations on Cisco Unity using the Octel dial IDs and telephone numbers you gathered from each office. Install the users for the Nebraska office. Disconnect the Nebraska office Octel server and connect the Cisco Unity server. Force name net emulation to replicate the user database. In three months repeat these steps at the next office.
D.
Create a new forest and new dial plan for all Octel node IDs and users. Install Cisco Unity and a Cisco Unity Bridge in the new Active Directory forest, then create a new serial number and dial ID for the Cisco Unity and Unity Bridge primary location information. Create delivery locations to Cisco Unity using the Octel dial IDs from your new dial plan for each office. Install the users for the Nebraska office. Force name net data synchronization to replicate the user database. In three months repeat these steps at the next office.
E.
Disconnect the Octel system and connect the Cisco Unity system.
