Chapter 5 Designing a Cisco Unity System with Domino as the Message Store

Unified Messaging Configurations

Cisco Unity requires Editor with Delete Documents permission for the address book that Cisco Unity monitors. A Cisco Unity server can monitor the address books for one domain, including Names.nsf and any secondary address book that may be supporting proxy/remote users (users who do not have mail files in the Domino domain).

For more information on permission requirements, see the applicable Cisco Unity installation guide at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.

Unified Messaging Configurations

In a Unified Messaging configuration, Cisco Unity does not own the directory or messaging data but instead uses existing directory (Domino address book) and message store information. The benefits of Unified Messaging include:

•Significantly reduced administrative overhead because the customer does not need to create and maintain separate accounts for e-mail and voice messaging applications.

•No dedicated infrastructure for a separate voice-messaging system. Cisco Unity uses the existing messaging infrastructure by voice-enabling the e-mail environment.

•Starting with Unified Messaging is administratively easier than starting with a Voice Messaging system and later migrating to Unified Messaging.

Unified Messaging, No Domino Cluster

		When you are setting up two or more Cisco Unity servers, the servers can be networked by using
		Cisco Unity Digital Networking. If the phone system has ports available, you can hook up more than one
		Cisco Unity server to each phone system. For more information, see Table 5-3.
Table 5-3		Server Requirements and Recommendations for a Unified Messaging Configuration
	Servers		Requirements and Recommendations
	Cisco Unity server		Each physical site that includes one or more Domino servers on which mailboxes for
			Cisco Unity subscribers are homed also includes at least one Cisco Unity server.
			Each Domino domain requires a Cisco Unity server. If you need to import Cisco Unity
			subscribers in different Domino domains, you must install a Cisco Unity server in each
			Domino domain and use Digital Networking between the servers.
	Domino address book server,		Domino servers must be in the same highly available and connected LAN as the
	message store server, and mail		Cisco Unity server.
	drop server
	Domain controller/global		There must be at least one DC/GC per physical site that includes a Cisco Unity server. If
	catalog server (DC/GC)		necessary, the Cisco Unity server can be the DC/GC.
	DNS server		There must be at least one DNS server per physical site that includes a Cisco Unity server.
			In sites with enough servers, we recommend two or more DNS servers.
	Media gateways (for phone		The PIMG or TIMG units can be connected to the Cisco Unity server by a LAN or a WAN.
	system integrations that include
	PIMG or TIMG units
	Cisco Unified Communications		The Cisco Unified Communications Manager (CM) (formerly known as Cisco Unified
	Manager servers		CallManager) and Cisco Unity servers can be connected by a LAN or a WAN.
