Where Cisco Unity Stores Data

The directory replicates the information to all Domino servers in the domain (for Domino) or domain controllers and global catalog servers in the forest (for Exchange), which ensures that Cisco Unity has the required access to information.

For detailed information on adding two or more Cisco Unity servers to the same Domino domain or Active Directory forest, see the Networking Guide for Cisco Unity at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_feature_guides_list.html.

Enabling Communication (Interoperability) Between Cisco Unity and Other Voice Messaging Systems

Cisco Unity supports several methods for allowing communication between Cisco Unity and other voice messaging systems:

•VPIM (Voice Profile for Internet Mail) is a digital protocol for transferring voice messages between different voice messaging system. To send and receive voice messages by using VPIM, the customer creates a delivery location object for each remote voice messaging system. The third-party voice messaging server must adhere to the VPIM v2 protocol.

As with the primary location objects, which allow one Cisco Unity server to send messages to subscribers who are associated with another Cisco Unity server, delivery location objects contain the information necessary for Cisco Unity subscribers to exchange voice messages with people who are using another voice messaging system.

•The Audio Messaging Interchange Specification analog (AMIS-a) protocol provides an analog mechanism for transferring voice messages between different voice messaging systems. To send and receive voice messages by using AMIS, the customer creates a delivery location object for each remote voice messaging system.

•The Cisco Unity Bridge acts as a networking gateway between Cisco Unity servers and Octel servers. The Bridge communicates with Octel servers by using the OctelNet analog protocol; it communicates with Cisco Unity servers by using the Digital Networking protocol, which is based on the VPIM protocol, with proprietary extensions.

Because the servers use different protocols, the Bridge uses nodes to translate messages as appropriate for each server. For the Octel node, the Cisco Unity Bridge maintains a table that contains the Octel server name, unique serial number, and phone number. For the Cisco Unity node, the Bridge maintains another table that contains the Cisco Unity server name, assigned serial number, and domain name. By using these two tables, the Cisco Unity Bridge server can, for example, receive a message from an Octel node, look up the routing information from the

Cisco Unity node table, reformat the information for the destination Cisco Unity node, and then send the message to the Cisco Unity node.

Data That Appears in Both the SQL Server 2000 Database and in the Address Book/Directory Is Automatically Synchronized

Some Cisco Unity information is stored in both the SQL Server 2000 database and in the address book/directory. This data can be changed both from within Cisco Unity (for example, subscriber information can be changed by using the Cisco Unity Administrator), and from outside Cisco Unity (for example, subscriber information can be changed by using Active Directory Users and Computers).
