Chapter 5 Designing a Cisco Unity System with Domino as the Message Store
Overview of Cisco Unity with Domino and Notes
–A secondary address book is an address book from which subscribers can be imported but that does not home default Cisco Unity accounts. You can choose a secondary address book, if any, in the Cisco Unity Administrator.
–Monitored address books may be needed when there are multiple Cisco Unity servers that will be set up for Digital Networking. For more information, see the “Managing Monitored Address Books” section in the “Digital Networking” chapter of the Networking Guide for Cisco Unity Release 5.x at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_feature_guides_list.html.
•Message store servers are the Domino servers that home the mail files for Cisco Unity subscribers. Domino administrators configure mail files for Domino users.
•The mail drop server is the Domino server that the installer specifies while installing IBM Lotus Notes on a Cisco Unity server. Cisco Unity delivers all voice messages to Mail.box on the mail drop server for routing.
Windows Domains and Domino Domains
A Cisco Unity server can be either a domain controller or a member server in a Windows Server 2003 or Windows 2000 Server domain. If the Cisco Unity server is a member server, it should reside in the same highly available and connected network as a domain controller for that domain.
The customer needs at least one Cisco Unity server for each Domino domain that will home Cisco Unity subscribers.
Server Placement
Revised May 6, 2008
Note the following best practices for placement of Cisco Unity servers and the servers that Cisco Unity relies on:
•The Cisco Unity server should reside in the same highly available and connected network as the address book servers, the message store servers, and the mail drop server, or the customer will experience delays in message access, in directory replication, and in directory lookups.
•Ensure that Cisco Unity can resolve server names to IP addresses. If this is not possible on a given network segment, consider adding the necessary resource or moving the Cisco Unity server to a segment that provides easy access to these services.
•Cisco Unity can coexist with firewalls. However, note that Cisco Unity should never be deployed outside of a firewall. Doing so can expose the Cisco Unity server to unwanted intrusion from the Internet, even if the server is hardened.
When failover or standby redundancy is configured, the Cisco Unity servers cannot be separated from one another by a firewall. They also cannot be separated by a firewall from:
–Domino servers on which mailboxes for Cisco Unity subscribers are homed.
–The Domino server that Cisco Unity monitors for changes to the directory.
–The Domino server to which Cisco Unity sends voice messages. (This is the Domino server that the installer specifies while installing IBM Lotus Notes on the Cisco Unity server. Cisco Unity delivers all voice messages to Mail.box on this server for routing.)
–The domain controller on which the Cisco Unity installation and services accounts were created.
