Networking in Cisco Unity

Overview: Networking in Cisco Unity

In Cisco Unity, “networking” is the general term for messaging between Cisco Unity servers, and

between Cisco Unity and other voice messaging systems. The term networking has a broad definition

that encompasses the following ideas:

•

Subscribers associated with one Cisco Unity server can use the phone to send voice messages to:

–

Subscribers associated with another Cisco Unity server.

Individuals with access to a computer connected to the Internet.

Individuals who use a voice messaging system other than Cisco Unity.

•

Unidentified callers can find any subscriber in the phone directory and leave a voice message.

Depending on the phone system and network configuration, unidentified callers who reach the

Cisco Unity automated attendant or directory assistance can be transferred to any subscriber phone,

even to the phone of a subscriber who is not associated with the local server.

See the following sections:

•

Networking Options, page 1-1

Message Addressing Options, page 1-2

Locations and External Subscribers, page 1-3

Networking Options

The main goal of networking in Cisco Unity is to deliver messages from a Cisco Unity server to a target,

and to deliver messages from the target to Cisco Unity. The networking options available in Cisco Unity

are defined according to a combination of the message transport mechanism and the target, as shown in

Table 1-1.

Table 1-1

Networking Options

Networking Option

Description

Digital Networking

Allows messaging among multiple Cisco Unity servers connected to a single, global directory.

That is, the Exchange partner servers must be in the same Active Directory forest. Message routing

is done by Exchange.

Message Addressing Options

Table 1-1

Networking Options (continued)

Networking Option

Description

Internet Subscribers

Allows messaging with individuals over the Internet or any TCP/IP network by using SMTP. The

recipient receives the message as an e-mail with a WAV attachment. Internet subscribers can have

local extensions, recorded voice names, and greetings, and be listed in the directory, but they do

not have mailboxes in the local Exchange network. Messages are addressed to Internet subscribers

as they are to regular subscribers, but the messages are sent to the e-mail address that you specify

when creating the Internet subscriber account.

Trusted Internet

Subscribers

Trusted Internet subscribers are Internet subscribers that are trusted with decrypted secure

messages. Trusted Internet subscribers must be associated with a Trusted Internet Location. Secure

messages to Trusted Internet subscribers are decrypted by the Cisco Unity Voice Connector for

Microsoft Exchange before they are sent by the Exchange server. (Messages to regular Internet

subscribers are sent directly by the Exchange server and cannot be decrypted and therefore cannot

be played by the recipient.)

AMIS

Allows messaging with other voice messaging systems that support the Audio Messaging

Interchange Specification analog (AMIS-a) protocol. In essence, the sending voice messaging

system calls the receiving voice messaging system, there is an exchange of DTMF tones as defined

by the protocol, the sending system plays the message, and the receiving system records it.

Bridge

Allows messaging between Cisco Unity and an Octel system on an Octel analog network by using

the Cisco Unity Bridge. The Cisco Unity Bridge acts as a networking gateway between

Cisco Unity and the Octel system, and allows the systems to exchange voice and fax messages.

Messaging between Cisco Unity and the Bridge is done over the Internet or any TCP/IP network

by using SMTP. Messaging between the Octel servers and the Bridge is done by using the Octel

analog networking protocol. The Bridge must be installed on a separate and dedicated platform.

VPIM

Allows messaging with other voice messaging systems that support the Voice Profile for Internet

Mail (VPIM) protocol. VPIM allows different voice messaging systems to exchange voice, text,

and fax messages over the Internet or any TCP/IP network. VPIM is based on SMTP and the

Multi-Purpose Internet Mail Extension (MIME) protocol. VPIM Networking can be used for

messaging between Cisco Unity servers that access different directories, between Cisco Unity and

Cisco Unity Express, and between Cisco Unity with Exchange and Cisco Unity with Domino

systems.

Message Addressing Options

With AMIS, Bridge, and VPIM Networking, you can set up different addressing options, as follows:

•

Blind Addressing—With blind addressing, Cisco Unity has the information it needs to send

messages to the remote voice messaging system, even though the recipient mailbox number, text

name, and recorded name are not in the directory.

•

“External” Subscribers—You create AMIS, Bridge, and/or VPIM subscribers on the local

Cisco Unity server to correspond to subscribers on the remote voice messaging system. These

external subscribers (also referred to as “proxy users” or “remote subscribers”) can have local

extensions, recorded voice names, and greetings, and can be listed in the directory. However, they

do not have mailboxes in the local Exchange network. Messages are addressed to an external

subscriber as they are to a regular subscriber, but the messages are sent to the applicable mailbox on

the remote voice messaging system. External subscribers have corresponding Active Directory

contacts.

Locations and External Subscribers

•

A Combination—The various ways of sending and receiving messages, as detailed in Table 1-1, are

not mutually exclusive. For example, if the Cisco Unity servers in your organization are set up to

access a global directory (and thus can make use of the Digital Networking option), you can still add

Internet subscriber accounts for contractors working at home. In addition, if you are migrating users

from an existing voice messaging system to Cisco Unity in stages, you can add AMIS, Bridge, or

VPIM connectivity to the mix. Figure 1-1 depicts a configuration that uses a mix of the various

networking options.

Locations and External Subscribers

Regardless of which networking option you choose, the setup process is similar.

For each networking option, you customize the settings for the primary location. Each Cisco Unity

server has a default or primary location, which is created during installation and which cannot be deleted.

The primary location contains information that identifies the Cisco Unity server to other messaging

systems, which may or may not be Cisco Unity systems. See the “Overview: Primary Location Settings”

section on page 9-1 for more information.

To set up AMIS, Bridge, or VPIM Networking, you create delivery locations. A delivery location

contains the network information that Cisco Unity needs to send messages to other messaging servers,

which may or may not be Cisco Unity servers. You create a delivery location for each voice messaging

server with which the local Cisco Unity server will communicate.

Note

Trusted Internet Locations are a special type of delivery location. They do not contain information about

other messaging servers, but rather serve as a delivery location for Trusted Internet subscribers that are

trusted with decrypted secure messages. Based on the configuration settings of the Trusted Internet

Voice Connector

Location, messages are decrypted by the Voice Connector before they are sent by Exchange over the

Internet or any TCP/IP network via SMTP. (Messages to regular Internet subscribers are sent directly by

the Exchange server and cannot be decrypted and therefore cannot be played by the recipient.)

Optionally, you can also create “external” subscribers (that is, AMIS, Bridge, and/or VPIM subscribers).

The messages for external subscribers are stored externally to the Cisco Unity voice message store.

When creating an external subscriber, you specify a delivery location that the external subscriber is

associated with so that Cisco Unity has the information it needs to send messages to them.

Voice Connector

The Cisco Unity Voice Connector for Exchange is a Cisco Unity networking component that enables

messaging between Cisco Unity servers and other voice messaging systems.

The Voice Connector for Exchange 2000 can be used when your network consists only of Exchange 2000

or Exchange 2003 servers, or a mixture of Exchange 2000, Exchange 2003, and Exchange 2007 servers.

Caution

The Voice Connector for Exchange 2000 can be installed on an Exchange 2000 server or an Exchange

2003 server, but it cannot be installed on an Exchange 2007 server.

The Voice Connector performs the following functions:

•

AMIS Networking—The Voice Connector routes voice messages to the applicable

UAmis_<Servername> mailbox for outgoing analog delivery. Incoming AMIS voice messages

received by the Cisco Unity AMIS bridgehead are routed to the Voice Connector for processing.

•

Bridge Networking—The Voice Connector performs the message conversion and address translation

that allows Cisco Unity to exchange messages with the Bridge server.

VPIM Networking—The Voice Connector performs the message conversion and address translation

that allows Cisco Unity to exchange messages with other Cisco Unity servers or other voice

messaging systems by using the VPIM protocol. VPIM Networking also provides messaging

between:

–

Cisco Unity servers that access separate directories

Cisco Unity with Domino systems and Cisco Unity with Exchange systems

Cisco Unity and Cisco Unity Express

Note that the Voice Connector is not needed with Digital Networking because the Cisco Unity servers

access the same directory.

The Voice Connector ships with Cisco Unity and is available on the Cisco Unity Voice Connector for

Exchange Software Download page, at

http://www.cisco.com/cgi-bin/tablebuild.pl/unity-voice-connector.

Active Directory Schema Extensions

A small subset of Cisco Unity data is stored in Active Directory. Therefore, before installing

Cisco Unity, the Active Directory schema must be extended. In addition to the schema extensions

required before installing Cisco Unity, the Active Directory schema must be extended before setting up

the following:
