Glossary

dialing domain A dialing domain is a collection of Cisco Unity servers that access the same directory and that are integrated with the same phone system or phone system network. (Note this includes Cisco Unity servers that are configured for dual integrations.) A dialing domain is a grouping scheme that allows Cisco Unity to handle call transfers from one Cisco Unity server to another. Within the dialing domain, subscriber extensions in Cisco Unity must be unique just as the phone extensions in the phone system must be unique. (Typically, a subscriber extension and phone extension are the same number.) With a networked phone system, subscribers dial a phone extension without having to dial a trunk access code or prefix when calling someone who is at another location in the phone network. In the same way, when grouped in a dialing domain, subscribers associated with one Cisco Unity server enter a subscriber extension when sending messages to subscribers associated with another Cisco Unity server.

Digital Networking A Cisco Unity networking option. Allows messaging among multiple Cisco Unity servers connected to a single, global directory. The Exchange partner servers must be in the same Active Directory forest. Message routing is done by Exchange.

directory

directory messages

The data store used by Cisco Unity, which contains information about subscribers, distribution lists, and locations. Cisco Unity stores data in Active Directory. During setup, you specify one Exchange server (the partner Exchange server) through which Cisco Unity communicates with other Exchange servers in the network. If the partner server is Exchange 2000 or Exchange 2003, Cisco Unity uses Active Directory.

Almost all of the information about subscriber accounts and other Cisco Unity objects is stored in a SQL database on the Cisco Unity server, rather than in the directory. However, a minimal amount of information about subscribers, distribution lists, and locations is also still stored in the directory, primarily to support Unified Messaging and networking.

Messages that contain directory information (name, voice name, and extension) about a subscriber. In Bridge Networking, directory messages are sent between the Cisco Unity Bridgehead server and the Bridge. Additionally, the Bridge participates in NameNet, and therefore it makes administrative calls to, and receives calls from, Octel nodes on the Octel analog network to share directory information. In VPIM Networking, depending on the settings for each delivery location, the Voice Connector may generate directory messages based on incoming VPIM messages and non-delivery receipts (NDRs). The Voice Connector sends the directory messages to the Cisco Unity Bridgehead server, where the CsVPIMConnector service processes them and creates, modifies, or deletes VPIM subscribers and the associated Active Directory contacts.

E

extension address

Also referred to as a remote address. The destination address created by Cisco Unity when sending a message to a recipient on another voice messaging system or a remote Cisco Unity server. The extension address is in the format: [<Type>:<DeliveryLocationDialID>_<RemoteMailboxNumber>]

where type can be AMIS, OMNI, VOICE, or VPIM. The Voice Connector parses the extension address to determine the routing path for the message.

external subscriber A Cisco Unity term for AMIS, Bridge, and VPIM subscribers, who do not retrieve their voice messages on the local Exchange network. Instead, messages for the external subscribers are sent to a remote voice messaging system.
